This Sunday morning was excellent, and almost perfect weather and water conditions were seen at Woodman Point, following a night and morning of strong Easterly winds at 15-20 knots. This did well at clearing the water conditions near Woodman Point and in nearby areas. The visibility was great, between 6 – 10m, best on the south side of this famous groyne. Brain corals sat around their usual places, manly near the tip of groyne, where large schools of Talmas, stripeys, and other small fish (including snappers and trevally) were feeding. Very large seahorses were seen, as well as a Pineapple fish hiding in-between stones, and even a Blue Devil. The water temperature was perfect, at >23C, so all of the 22 divers in our group inspected this not often-visited dive site for full 50 mins. Some jellies were present, but didn't bite.
Divers of almost all different experience levels were present, from Open Water Divers to the DM; many new OW divers joined our group today, and everybody enjoyed exploring this dive site. Thanks everyone for coming to this Manta Club dive! See you on next Manta Club events soon.
Thank you to everyone that came to the Perth Scuba Club Dive. We met at the store for a barbecue breakfast and safety briefing then headed to North Mole for the dive. Some dives went looking for the wreck while others stayed next to the rock wall. There was between 1.5 meters visibility at the start of the dive with quite a strong current further out and visibility increasing to 5 meters. The water temperature was about 20 degrees Celsius. There were lots of crayfish and fish seen.
Thanks to all the fantastic divers that came down to Sue’s Groyne for this weeks club, night dive! We had a big group with all different levels of experience and it was a blast! Water conditions were pretty standard with about 3 metre visibility. We were lucky enough to see the groyne’s resident occys and cuttlefish as well as a sting ray or two. To top it all off, we had instructor Nathan give us a show with his fire twirlers! All together a wonderful night!
Life happens. Sometimes, those vibrant underwater adventures take a backseat to the daily grind. But now, you're itching to get back beneath the waves. Whether it's been months or years since your last dive, there are steps to ensure you return to the ocean safely and confidently. Dive in as we explore how to reacquaint yourself with the beautiful world of scuba diving.
Before you leap off the boat, take a moment to reflect. How do you feel about diving back in? Everyone’s comfort level is different. Some divers can pick up where they left off, while others may need a bit more time. And that's okay! The key is to listen to your gut and proceed at your pace.
A refresher course is the most recommended step for anyone who’s been out of the water for an extended period. These courses, often known as "Reactivate" or "Scuba Tune-up", cover essential skills like buoyancy control, equipment setup, and safety procedures. Plus, they give you a controlled environment to shake off any rust and rebuild confidence.
Just as you wouldn’t drive a car that’s been in the garage for years without a quick check-up, the same goes for your scuba gear. Whether you own equipment or rent, make sure everything is in tip-top shape:
Remember, safe equipment means a safe dive.
For your first dive back, consider revisiting a familiar dive site. It'll be like catching up with an old friend! Diving in known territory can help you focus on re-familiarizing yourself with the act of diving instead of navigating a new environment.
Diving isn't just about the practical; there's some nerdy science behind it too. Brush up on dive theory, including decompression limits, dive table usage, and the effects of diving at altitude. Many online platforms offer quick and engaging theory refreshers, so you won't have to dig out those old textbooks.
If your previous dive buddy has since taken up mountain climbing or knitting, it's time to find a new one. Dive communities and local dive shops are great places to meet fellow enthusiasts. Having a reliable and understanding buddy can make your transition back into diving smoother and more enjoyable.
Getting back into scuba diving after a hiatus is much like riding a bike. With a bit of preparation and self-assessment, you'll soon rediscover the magic that lies beneath our oceans.
Remember, diving is about enjoyment and relaxation. Never rush the process; the sea isn’t going anywhere. Soon enough, you’ll be back to making bubbles, greeting fish, and reveling in the serenity that only the underwater world can offer.
Thinking of diving back into scuba after a break? Always prioritise safety and ensure you're well-prepared for a splashy comeback!
Thank you to everyone that came to the Perth Scuba Club Dive. We met at the shop for a barbacue breakfast then went to Kwinana Grain Terminal after hearing the report of good visability. The water was nice and flat and about 18 degrees in temperature. Visibility was 4 to 5 meters and an octopus and cuttlefish were seen.
Diving is fabulous, right? You get to float around like a modern-day astronaut, befriending fish and discovering Atlantis' long-lost cousin twice removed. But what if we told you there's a way to add some extra pizzazz to your underwater adventures? Enter Perth Scuba's PADI Rescue Diver Course! And no, it's not just about learning how to wrestle with octopi. 🐙
Remember that time you accidentally became a mermaid’s hairstylist because your buddy got entangled in some seaweed? 🧜♀️ No? Well, it’s bound to happen someday! The Rescue Diver course prepares you for such unforeseen underwater adventures and more.
We've all had those ‘Oops’ moments underwater: losing a fin, misplacing our buddy (come on, they were right there a second ago!), or getting intrigued by a fish and forgetting about air supply. It's all fun and games until it's not. With the Rescue Diver certification, you'll be trained to anticipate and manage problems, making sure everyone's underwater adventure remains *just* an adventure.
Sure, we all love being the hero that saves the day, but what about those moments when *you're* the one doing a little unintentional solo diving? The course isn’t only about rescuing others. It's equally about self-rescue and self-awareness, ensuring you can handle those "Oops, I did it again" moments with finesse.
Joining the Rescue Diver ranks isn't just about the skills; it's also a badge of honour. It's like upgrading from regular VIP to ultra VIP in the underwater world. You’re not just any diver now; you're a diver who’s ready for anything - from runaway regulators to dive-bombing dolphins.
There are dive shops, and then there's Perth Scuba. Our expert team not only teaches you the necessary skills but does so with flair, fun, and maybe a fishy joke or two. We pride ourselves on offering a comprehensive course that's packed with real-world scenarios. You won't just learn; you'll live the experience, ensuring you're ocean-ready in every sense.
So, while the fishy world down there is mesmerising, it doesn’t come without its quirks. Whether you're in it for the superhero cape or the peace of mind knowing you're prepared for any underwater curveball, Perth Scuba's PADI Rescue Diver Course is the logical next step in your diving journey. Dive deeper, dive safer, and always, ALWAYS, keep an eye out for those sneaky octopi. 🐙
Ready to take the plunge into the world of Rescue Diving? Dive into Perth Scuba and discover a whole new level of underwater adventures.
]]>This Sunday we had very good water conditions at Bulk Jetty (otherwise known as BHP Jetty), with no current and almost no waves. After getting some calories (from quality beef sausages) at the traditional Perth Scuba pre-Club-Dive barbecue, ten of the dedicated dive crew headed towards the Jetty. The visibility was excellent - maybe up to some 8-12 meters of visibility for the most part, enough to see plenty of schooling fish (snappers and trevallies), and plenty of “underwater furniture” often missing from the view due to murkier conditions.
Overall, this Club dive was (as always) a great meeting of enthusiastic divers of all experience levels, and it was fun. The water temperature was already between 17-18C.
Thanks everyone for coming to this Manta Club dive! See you on next dives soon.
Wednesday night saw us return to what I call Perth’s Bermuda Triangle for dive gear. For those of you who aren’t old enough to remember the Bermuda Triangle was an area that was reported to make planes and boats disappear without a trace. In some instances they showed up years later. It was just one of the worlds unexplained things that doesn’t seem to be talked about these days.
Port Beach in Fremantle seems to have the same effect on dive gear. Although the go to place to find some awesome undersea critters like Weedie Sea dragons and PJ sharks I have seen more dive gear lost here than anywhere else. Getting out past the shore break can be challenging at times and many a diver has fallen victim, losing fins, masks and an assortment of other gear.
Wednesday was a great night with a smallish shore break but still a little challenging to get past. No gear was lost and although visibility wasn’t as good as we have seen there in the past, our divers saw a great range of old favourites. Seadragons, Port Jacksons, Squid and the ever popular Western Smooth Boxfish. There was even a ray or two.
There have been some pictures posted on the Manta Club Facebook page. Are you a member of the Perth Scuba Manta Club page? If not, do a search and find us. It is where all the cool club stuff happens. We have giveaways and all the up to date goss on what is happening around Perth.
Don’t forget we have club dives every Sunday, meet at Perth Scuba at 9 am and the Wednesday night dives for the adventurous among us. The weather is getting better so things are starting to get exciting again.
Rottnest Island, a picturesque locale just a short boat ride from Fremantle, is a renowned hotspot for divers seeking vibrant limestone reefs, turquoise bays, and of course, the opportunity to dive with the mysterious Grey Nurse Sharks.
Contrary to their fearsome appearance, Grey Nurse Sharks are largely docile, posing no threat to humans unless provoked. With their streamlined bodies reaching up to 3.2 meters in length, watching these majestic creatures glide effortlessly through the water is a sight to behold.
As you descend into the waters surrounding Rottnest Island, the first sight that greets you is the thriving limestone reef ecosystem. Colourful fish dart about, and with a bit of luck, playful sealions might make an appearance. But the real showstopper is, without a doubt, the Grey Nurse Sharks. Observing them in their natural habitat, circling lazily among the underwater rock formations and caves, is an experience that's both serene and exhilarating.
vulnerable in WA (critically endangered in the East coast). Guidelines are in place to protect them from current threats to the species believed to be incidental catch from commercial fisheries and recreational fishing.
Scuba diving with the Grey Nurse Sharks at Rottnest Island isn't just another check on a diver's bucket list. It's an encounter that reminds us of the marine world's fragility and our role as custodians of these beautiful creatures. So, on your next trip to Rottnest Island, consider diving into this underwater adventure—you'll leave with a renewed sense of respect for the ocean and its remarkable inhabitants.

]]>Thank you to everyone that attended the Perth Scuba Club Dive. We met at the shop for a barbecue breakfast, then headed to Ammo Jetty for the dive. The conditions were less than ideal with a bit of surge, visibility of only a metre at best and a water temperature of 15 degrees. As a result a lot of the divers used the dive as a training opportunity, working on buoyancy, breath control and navigation. Even though the visibility was poor there were a couple of seahorses still seen.
If you're a passionate scuba diver seeking thrilling underwater adventures and vibrant marine life, you're in for a treat in Perth, Western Australia. Nestled along the breathtaking coast of the Indian Ocean, Perth offers an array of spectacular dive sites that cater to divers of all levels. As your trusted PADI dive shop in this region, Perth Scuba is excited to present "The Ultimate Guide to Scuba Diving in Perth," featuring top dive sites and the awe-inspiring marine life that calls these waters home.
A short boat ride from Fremantle lies Rottnest Island, a diver's paradise boasting clear waters, mesmerising limestone reefs, and captivating turquoise bays. The marine diversity here is unparalleled, making it a must-visit destination for every scuba enthusiast. Encounter playful sea lions, graceful rays, and colourful schools of fish as you explore popular dive sites such as the Crystal Palace, Shark Cave, and Kingston Reef.
Delve into history by exploring the HMAS Swan, a decommissioned naval destroyer that was deliberately sunk off the coast of Dunsborough (2 hours drive from Perth). This impressive artificial reef now serves as a haven for an array of marine species, including wobbegong sharks, schools of globe fish, and Samson fish. This dive site offers an unparalleled opportunity to witness the fascinating fusion of nature and man-made structures beneath the waves.
It's a unique underwater destination brimming with a diverse array of marine life. Located in Cockburn Sound, near the city of Rockingham, the site gets its name from its history as a former ammunition jetty, used by the Australian Navy to offload munitions from ships. Over time, this structure, along with some discarded debris, has evolved into a vibrant marine ecosystem, making it an exceptional dive site for both beginners and seasoned divers.
The main allure of Ammunition Jetty is its varied and colourful underwater residents. Divers often encounter an assortment of critters, including nudibranchs, seahorses, octopuses, cuttlefish, and a multitude of fish species. The area around the jetty pillars teems with life, where soft corals, sponges, and other invertebrates have taken hold. Thanks to the site's easy access from the shore and its relatively shallow depth, which ranges from 3 to 8 metres, it's also a popular spot for night diving and underwater photography. Ammunition Jetty represents the true embodiment of a hidden treasure, transforming a man-made structure into a flourishing marine habitat.
Although a few hours' drive from Perth, Ningaloo Reef is a natural wonder that shouldn't be missed. Renowned for its annual whale shark migration and diverse coral formations, Ningaloo offers a once-in-a-lifetime experience to swim alongside these gentle giants and explore the vibrant reef system. The opportunity to witness manta rays, humpback whales, leopard sharks and dugongs only adds to the allure of this UNESCO World Heritage site.
Perth's diverse aquatic habitats harbor an array of marine life that will leave you awe-struck. Keep an eye out for elegant weedy sea dragons, the iconic blue-ringed octopus, and the enigmatic Wobbegong sharks camouflaged among the limestone ledges. You may also encounter playful dolphins, majestic turtles, and if you're lucky, the elusive and gentle leafy sea dragons.

So, gear up, dive in, and let Perth Scuba be your gateway to the underwater wonderland that lies just off the shores of Western Australia. Happy diving!
This Sunday we had nice water conditions at BHP Jetty (now more widely known as Kwinana Bulk Jetty), even following a strong swell and rains for a few days before. After enjoying some quality beef sausages served with select choice of sauces at the traditional Perth Scuba pre-Club-Dive barbecue, a total of ten of the most-dedicated all-seasons dive crew headed towards BHP Jetty. We knew the water was going to be refreshing (15C) and the visibility wasn't guaranteed at all. We were rewarded to see that the visibility was actually quite good - some 5-8 meters for the most part. Saw plenty of schooling fish (small and medium size snapper), and underwater inhabitants such as nudibranchs, and a cuttlefish. We all had good fun.
This Club dive was (as always) attended by very enthusiastic divers of all experience levels, including buddy pairs composed of Perth Scuba's recent Open Water graduates and new Manta Club members, and it was a great experience. Some of us (myself included) wore new wing BCDs (at least 4 divers had newly-acquired wings), enjoying some new learning and new freedom in underwater moves. Special thanks for the great underwater photography supplied by Perth Scuba Divemaster Guy.
Thanks everyone for coming to this Manta Club dive! See you on next dives soon.

Diving enthusiasts around the world are drawn to the mesmerizing beauty and tranquility of the underwater world. As the popularity of scuba diving continues to rise, so does the importance of preserving and protecting the delicate marine ecosystems we explore. At Perth Scuba, we firmly believe in promoting sustainable scuba diving practices to ensure that future generations can continue to experience the wonders of the ocean. In this article, we share how Perth Scuba is committed to eco-friendly initiatives and the steps we take to make a positive impact on the marine environment.
A crucial aspect of our eco-friendly diving approach is educating our divers about the fragility of our soft coral reefs and marine life. Our dive briefings focus on responsible diving techniques that minimize contact with the delicate underwater ecosystems. We emphasize buoyancy control and encourage divers to avoid touching or disturbing marine organisms. By educating our divers about the importance of reef conservation, we aim to instill a sense of responsibility for protecting these invaluable habitats.
We take great pride in maintaining a "leave no trace" policy during our dive excursions. Our dive shop provides course divers with reusable water cups to minimize single-use plastic waste. We also ensure that all trash generated during dive trips is properly disposed of onshore, adhering to the strictest waste management practices. By reducing our ecological footprint, we hope to set an example for our divers and inspire them to adopt more sustainable habits in their everyday lives.
At Perth Scuba, we actively support various ocean conservation initiatives and collaborate with local environmental organisations. Through partnerships and donations including PADI AWARE, we contribute to reef restoration projects, marine research, and coastal clean-up efforts. Our goal is to actively participate in the preservation of the marine environment that provides us with so much joy and inspiration.
As avid scuba divers, we are privileged to encounter a diverse array of marine critters. We strictly adhere to guidelines established by marine authorities to ensure responsible interactions with wildlife. Our dive instructors are trained to maintain a safe distance from marine animals and to refrain from touching them. This approach not only safeguards divers' safety but also respects the natural behaviors of marine life.
Our commitment to sustainability extends beyond our dive trips. We actively seek out and collaborate with dive operators and suppliers who share our eco-friendly values. From eco-conscious resorts to equipment manufacturers that prioritize environmentally friendly materials, we strive to support businesses that align with our vision of sustainable scuba diving.
At Perth Scuba, we believe that eco-friendly diving practices are not just an option; they are an obligation to protect and conserve the marine environment we cherish. By implementing responsible diving techniques, supporting conservation initiatives, and making conscious decisions, we hope to lead by example and inspire others to join us on our journey towards a more sustainable future for scuba diving. Together, we can ensure that the underwater world remains a vibrant and thriving ecosystem for generations to come.
Join us in our commitment to sustainable scuba diving practices and experience the wonders of the ocean while preserving its natural beauty!
]]>In the fast-paced world we live in, stress and anxiety have become an integral part of our daily lives. As we strive to achieve a work-life balance, it's essential to find healthy outlets that promote mental well-being. One such activity that offers a unique escape from the pressures of modern life is scuba diving. Beyond the captivating underwater world, scuba diving has proven to be an effective therapeutic tool, providing a myriad of mental health benefits that contribute to a calmer and more balanced state of mind. In this article, we'll explore the psychological advantages of scuba diving and how it can positively impact mental health.
Scuba diving immerses individuals in an entirely different realm, where the worries of everyday life seem to dissipate. The slow, rhythmic breathing required while underwater induces a meditative state, akin to mindfulness practices. Focusing on the present moment and the breathtaking beauty of marine life creates a profound sense of tranquility, which helps reduce stress and anxiety. As divers become more attuned to their breathing and surroundings, they experience a heightened sense of relaxation, leading to decreased levels of the stress hormone cortisol.
Exploring the underwater world opens up an exciting avenue for adventure, curiosity, and exploration. The sense of wonderment experienced while diving fosters a childlike enthusiasm, breaking the monotony of routine life. Engaging in adventurous activities like scuba diving triggers the release of dopamine and endorphins in the brain, often referred to as "feel-good" chemicals, which elevate mood and promote a positive outlook on life.
Scuba diving is often a group activity, which fosters social bonding and a sense of camaraderie among participants. Sharing the awe-inspiring sights and experiences underwater creates lasting memories and deep connections with like-minded individuals. For those struggling with feelings of isolation or loneliness, joining a scuba diving community can provide a supportive network and a sense of belonging, which are crucial for overall mental well-being.
For many, scuba diving is an activity that challenges personal fears and limitations. Overcoming anxieties related to deep waters or marine life fosters a profound sense of accomplishment and empowerment. This newfound resilience can extend beyond the diving experience and positively influence how individuals approach challenges in other aspects of life. Facing fears in a controlled and supportive environment can lead to increased self-confidence and a willingness to take on new challenges.
Scuba diving demands a level of focus and mental acuity, as divers must navigate through varying underwater terrains and monitor equipment. This mental stimulation is akin to a puzzle-solving exercise, enhancing cognitive function and promoting mental sharpness. Engaging in mentally stimulating activities is associated with a reduced risk of cognitive decline and may contribute to overall brain health in the long term.
In the depths of the ocean lies a therapeutic sanctuary that offers respite to weary minds. Scuba diving, beyond being an exhilarating recreational activity, offers a plethora of mental health benefits. From promoting mindfulness and reducing stress to fostering social connections and resilience, this underwater adventure grants a unique opportunity for personal growth and mental well-being. If you're seeking an escape from the pressures of life while indulging in an awe-inspiring experience, scuba diving might just be the dive into serenity your mind needs. So, take a plunge into the mesmerising underwater world and witness the positive transformation it can bring to your mental health.
]]>This week saw us heading of to Ammo Jetty for the manta club dive. Meeting as usual at Perth Scuba for a feed and any necessary gear we headed of to Ammo Jetty where the weather was pretty good but visibility was a bit poor at about 2-3 m.
But we still had a good dive finding the usual array of fish resident to Ammo and some testing out new gear purchased in the morning. Thanks for coming dedicated winter divers!
Sunday 9 July 2023
This Sunday morning was excellent for diving, featuring great water conditions and visibility at Kwinana Grain Terminal. No waves, almost no wind (slight NW, ~ 10 knots or less). 10 of the committed all-seasons dive crew enjoyed the water (15C, but still looking like being on the temperature increase now) in the habitat of nudibranchs, octopus, and many other marine creatures. My 5mm Cressi Maya wetsuit was more than enough for ensuring comfort, with a minimum of wet undergarment (thick rashie) applied, allowing for a cosy 50-minute dive and feeling warm after exiting the water. The visibility was excellent, at near 10-15 m, as soon as we moved the first 40-50 meters out from shore. No buddy pairs could be separated due to water conditions, the visibility was almost wall-to-wall, covering the entire space of this magnificent dive site. With no ship docked at the end, our exploration of this site was unlimited. At least one octopus was seen (in hiding, though), and plenty of colourful fishes, including schooling catfish, a weird-looking variety of Leatherjacket, and an impressive Cuttlefish.
Divers of various different experience levels were present, and everybody enjoyed the dive. The visibility should still be good during the next few days, at least. Big thanks to Divemaster Guy for making a great video of this dive, some screenshots of which are included in this publication.
Thanks everyone for coming to this Manta Club dive! See you on next dives soon.
I have always said night dives bring out the beautiful critters and I was right for last Wednesday nights dive at the Omeo Wreck Trail. What a great pod of divers that turned up for a night in the water.
Conditions were near perfect and visibility was the best we have seen along the coast in recent weeks. Omeo is a relatively shallow dive but always puts on a good show of night time marine life. Cuttlefish, Cobbler and different varieties of squid were seen. Quite a few divers have taken to explore the world of hidden coral colours using UV lights. The underwater world glows with brilliant colour and the Coogee Marina Wall is a great place to explore.
Whilst still a little cool in the water it was an awesome night out. As winter moves on we are seeing more and more dry suits coming out of the cupboards. Even I was tempted and donned the Scubapro Everdry Neoprene dry suit. I’ve always thought they were more fuss and bother than they were worth but I have to say I am a bit of a convert now. I’m sure I’ll run a few more ‘test’ dives over the next few weeks.
Thank you to all the regular Manta Club members that attended and it was great to see some some of the divers that attend our Sunday dives take the plunge and join our night time adventures. There were smiles all around from those undertaking their first night dive and finding out being out there in the dark isn’t a scary as they thought.
If you are keen to give a night dive a try join us next Wednesday night. We are a pretty cool bunch, especially during winter……..If the cold is keeping you away, drop in to Perth Scuba and have a chat to the guys and girls in the shop about the options available for keeping warm. You might be surprised at what is available these days.
Safe diving and see you on our next adventure.
Thank you to everyone that came to the Perth Scuba Club Dive. We met at the store for a barbecue breakfast, then headed down to Bulk Jetty for the dive.
Condition were amazing with very little wind and flat waters. Visibility was about 5m and the water temperature was 16 degrees. There were heaps of nudibranch seen on this dive.
The river certainly turned on its winter charm on Wednesday night. Near perfect conditions saw 7 divers take to the depths.
With a reported temperature at the bottom of 14 degrees it certainly wasn’t for the faint hearted. Many pulled the dry suits out and were most appreciative of the comforts they bring. If you are diving through winter it is certainly something to consider.
We had both hunters and adventurers out there with a healthy catch of crabs and prawns for some and some cool critters found doing what they do. Yes, we did find seahorses, always an awesome find in the river.
Thank you to everyone that turned up for the night.
Remember we dive every Wednesday night both in the river and along the coast and then there is the Sunday morning club dives after breakfast at the shop. If you are keen to dive and meet new buddies come along.
Squid eyes are fascinating organs that have evolved to provide these marine creatures with exceptional vision. Squids belong to a class of mollusks called cephalopods, and their eyes are highly developed and specialized for their underwater environment.
Here are some key points about squid eyes:
Structure: Squid eyes have a similar basic structure to vertebrate eyes, with a lens, iris, and retina. However, they are different in certain aspects.
Large Size: Squid eyes are relatively large in proportion to their body size. Some species of squid have eyes that can reach up to 25 cms in diameter, making them the largest eyes in the animal kingdom.
Complex Lens: The squid's lens is rigid and elongated, unlike the flexible lenses found in most vertebrate eyes. This rigid structure helps maintain the shape of the eye underwater and prevents distortion caused by water pressure.
Excellent Vision: Squid have excellent visual acuity and can detect polarized light, allowing them to see objects clearly even in the dimly lit depths of the ocean. Their eyes are particularly adapted for detecting movement, which is crucial for hunting and avoiding predators.
Colour Vision: Squid have color vision and can perceive a wide range of colours. They possess a complex visual system that allows them to discriminate between different wavelengths of light.
Binocular Vision: Squid eyes are positioned on either side of their head, giving them a wide field of vision. Although each eye sees independently, the squid's brain processes the visual information from both eyes to create a composite image and provide depth perception.
Retina and Photoreceptors: The squid's retina contains two types of photoreceptor cells—rods and cones. Rods are responsible for low-light vision and detecting motion, while cones are specialized for color vision and high-resolution details.
Eye Movement: Squids can move their eyes independently of each other. They can rotate their eyes and change the orientation to focus on specific objects or track movements in different directions.
Overall, squid eyes are remarkable adaptations that allow these cephalopods to thrive in their marine environment. Their large size, complex lens, excellent vision, and unique features contribute to their ability to navigate, hunt, and communicate effectively underwater.

Thank you to everyone that came to the Perth Scuba Club Dive. We met at the store where an amazing breakfast was provided. We then headed to Sue's Groyne as it was protected from the wind. The water conditions were pretty average, there was a bit of swell, visibility of only about 1 meter and water temperature of 17 degrees. There were only a couple of nudibranchs seen during the dive.
Another cold Perth night but what a night for diving. Our Manta Club members went out at Bulk Jetty in near perfect conditions. The wind was down and the water flat.
With good vis they came back with tales of huge eels, squid and the usual favourites that Bulk Jetty has on offer.
Well done to Nathan for coming along for his first night dive. I’m sure we will see him back for plenty more.
Don’t let the cold stop you from diving. We have some of the best vis and conditions to explore in Perth over the winter. The Swan River even becomes an awesome place to play.
The Manta Club dives run all year round on Sundays and Wednesday nights. Come along and explore with us.
Sunday morning saw a range of divers from just qualified open water to Divemasters turn up for Manta club dive. After BBQ and brief we headed off to Bulk Jetty for the club dive.
Was a little bit choppy on surface but when descending was pretty good vis and usual array of life. Thanks to everyone for coming along!
The swells and strong winds gave us a long pause recently, and we had perfect sunny conditions at many coastal locations, and at Point Peron, it all looked really good today, with a very slow N-NE winds overnight. After our barbeque, we headed there to see near-flat water surface and the visibility was at least 10-15 meters. The main attraction there was (as usual) a tricky possibility of finding some excellent caverns filled with teams of large fish of several species. Many have been in there, but some of us only find these caves on good visibility days. We found some caverns, adding to each diver's number of caverns visited there (few really know how many in total are even there). An octopus of large proportions was witnessed by myself, raising questions whether it could emit enough “ink” to hide. Also, schools of quite small tevallies as well as groups of rather large Samsonfish were spotted near caverns. We had a great dive, in water still being warm at 18C.
The Manta Club crew (eleven of us attending the Club dive today, including some new divers) enjoyed this spectacular diving spot at all available depths ranging from a few meters to about 8-9m just outside the reef line, after a good swim in the NW direction.
Thanks everyone for coming to this Manta Club dive! See you on next dives soon!
Perth Scuba is offering free drysuit dives and expertise - come join us and explore a totally new way to scuba dive!
Bring your dive gear including cylinder (or hire what you need at Perth Scuba) and we'll head to our local swimming pool 10am to try diving completely dry!
]]>Manta Club dive at Jervoise Bay – great visibility on an autumn day, the water is still quite warm
]]>This Sunday morning was great for diving, and the weather was enjoyed by all 12 of our divers on the Club Dive list today. The water conditions were nice, at 18 C without a ripple. The visibility in the water was between 10-15 meters or so, depending on the section of the dive site. The shallow part of dive site offered swimming-pool-like visibility. We were surrounded by schools of small stripey fishes, few talmas, plenty of morwong, and many colourful soft corals we seen also, including multiple small-sized Brain corals that can escape detection at less visibility than what we had today. Among the more noteable soft corals were translucent Dendronyphtias near the end of groyne, at near 11m. Some divers saw more than me; results may follow from our all-seasons hardened dive crew soon. We heards reports of sighting what looked like “black squid”; possibly that wa sa cuttlefish lookalike.
Divers of many various experience levels were present, and everybody said they enjoyed exploring this not-so-ordinary dive site. Several new Manta Club divers joined our crew today, and hopefully seen some things of interest in the water. Thanks everyone for coming to this Manta Club dive! See you on next dives soon.
Tonight’s dive at Woodman Point was a diver’s dream. The water was glass off, and not even a hint of a breeze. The water was crystal clear, visibility was as far as your torch would allow. What an absolutely beautiful dive this was.
We saw cuttlefish, octopus, 2 huge balls of juvenile striped catfish, a couple of crays, a couple of juvenile snook which was a big surprise, and at the end of the Groyne we were delighted by every single size and colour of seahorse you could imagine. The water temperature is dropping for sure, 4 of us were in dry suits and the rest in wetties … they were the ones who came out looking like Smurfs!
If you were ever considering investing in a dry suit, now is the time. The ocean is waiting… see you soon at another Perth Scuba Manta Club dive!
