Marine wildlife fleeing to poles due to global heating as Australian oceans face ‘uncharted’ future. The rules that we’ve been relying on for ocean protection and conservation… they’re going to have to evolve. www.theguardian.com/environment/...

At COP30 numbers are jaw-dropping: 1 in 25 participants is a fossil-fuel lobbyist. If change is going to come from within, then this isn’t a cameo, it’s control. We need institutional integrity & transparency - not just token seats at the table. www.theguardian.com/environment/... #ClimateAction

“The National Marine Fisheries Service announced today that it will form a federal task force to curb Pacific humpback whale entanglements in fishing gear. Dozens of humpbacks are entangled off the Pacific Coast every year.” biologicaldiversity.org/w/news/press...

Australia is reshaping its national environment laws, but EPBC Act reforms still leave big gaps. Weak standards, political exemptions, & no accountability for climate impacts = risks for nature. Strong, enforceable protections matter - especially now. biodiversitycouncil.org.au/resources/ge...

Heartbreaking loss: juvenile humpback whale (~8m) entangled & drowned in shark net off NSW coast. Shark nets don’t necessarily do what we assume -- protect beach-goers -- and pose serious risks to sharks, whales, dolphins, turtles, and other non-target animals. www.theguardian.com/environment/...

Friends, I am offering a free online 2-hour crash course in how to write and publish a scientific paper, perfect for early career scientists and students considering writing their first paper soon. All information can be found in this link: www.southernfriedscience.com/im-offering-... 🧪🌎🦑

Newborn reef sharks are ninja swimmers! 🥷🦈⚡️ Our latest study shows pups can dodge predators in under 20ms. A reminder of how amazing—and vulnerable—shark nursery habitats are. Read more via @jcuofficial.bsky.social : www.jcu.edu.au/news/release...

The Great Barrier Reef is a global icon & national treasure, but it's also a frontline casualty of climate change. What happens to the Reef is a warning signal for marine ecosystems globally. We still have time — but only if we act now. @jcuofficial.bsky.social 📸 @physiologyfish.bsky.social

New paper in Ecology & Evolution: analysed 187 species of rays & skates to explore patterns of sexual size dimorphism. Turns out SSD in rays doesn’t follow the same rules as in sharks. ❓Differences in reproductive strategies❓ 🔗 doi.org/10.1002/ece3... #SharkScience #Evolution #MarineBiology

Indeed... one of the many mysteries we still have to unravel! We're super happy to share this paper led by @jcuofficial.bsky.social PhD candidate Joel Gayford!

I love that not all #sharks even undergo TI (tonic immobility) because it makes it even more curious! There's so little info on all of this in general that any new info creates a lot of questions :) @physiologyfish.bsky.social 🧪 🦈 🐟 🦑 Recent paper about this: link.springer.com/article/10.1...

We are super proud of this paper led by @jcuofficial.bsky.social PhD student @joelgaylard.bsky.social - so cool that #sharks follow these centuries-old mathematical scaling 'rules' almost perfectly!!

More coverage, this time from SciTechDaily, of paper from Joel Gayford and @physiologyfish.bsky.social on #shark size/surface area ratios scitechdaily.com/sharks-follo...

You know how a #shark goes immobile or "tonic" when flipped over on its back? TIL that isn't true for all species. A new study from Joel Gayford and @physiologyfish.bsky.social says: three different orders of shark..seem to have all lost the ability to go into tonic www.jcu.edu.au/news/release...

Fear? We know when one is faced with uncertainty the response is fight/flight/freeze… Sharks do not swim upside down. Holding them this way could trigger their nervous system…

Some sharks freeze when you turn them upside down – and there’s no good reason why... anymore. New study 📄 theconversation.com/sharks-freez... by Gayford & Rummer at @jcuofficial.bsky.social #sharkscience #evolution

New @jcuofficial.bsky.social study — tonic immobility in sharks may be ancient evolutionary baggage — not a survival trick. 📄 doi.org/10.1007/s111... Some sharks freeze when flipped over. Does it help them survive? Probably not. Maybe leftover from their ancient ancestors. #SharkScience #Evolution

Great article written by Joel Gayford & @physiologyfish.bsky.social on our recent paper in Royal Society Open Science Journal using #3D models to study shark scaling. Credit also to co-authors Johnson Martin & Andrew Chin as well. theconversation.com/sharks-come-...

New paper out today! 🦈 We tested whether blacktip reef shark dorsal fins are reliable for photo ID – they are! ✅ Stable over time ✅ Unique among individuals 📍Long-term dataset from French Polynesia Led by Physioshark 🔗 doi.org/10.1111/jfb.... #SharkScience #MarineBiology @jcuofficial.bsky.social

This very likely has some important implications for reconstructing Carcharocles megalodon!

🦈 #shark A new study from JCU researchers Joel Gayford and @physiologyfish.bsky.social has examined the surface area to volume ratio of 54 species of shark, finding that it tends to follow the same trend we expect to see for individual cells royalsocietypublishing.org/doi/10.1098/...

Further coverage, this time from The Conversation, of new paper Joel Gayford and @physiologyfish.bsky.social showing that "sharks seem to converge on the same basic body plan when it comes to surface area and volume"

Sharks: 450 million years of toothy excellence, still following a centuries-old geometry rule. Meanwhile, you’re still using that “passionate self-starter” line on your resume. Excellent shark content & summary of a new study! #OceanHoptimism #SharkMath #EvolutionaryFlex #UpdateYourResume

Sharks come in many different shapes and sizes. But they all follow a centuries-old mathematical rule theconversation.com/sharks-come-...

Sharks just proved the 2/3 scaling law. 🦈📏 Using 3D modelling of 54 species, we found sharks follow the expected surface area-to-volume relationship almost perfectly — validating a key physiological theory. 📄 doi.org/10.1098/rsos... 📸 Rachel Moore 📍 @jcuofficial.bsky.social #SharkScience #shark
