🦈 Ep 3 Athletes of the Reef is out! New research led by Joel Gayford shows tonic immobility isn’t universal in sharks - for some species, “playing dead” may be a fatal mistake. 🎙️ Spotify: open.spotify.com/episode/05xT... 📄 Paper: doi.org/10.1007/s111... #SharkScience #MarineBiology 📸 Rachel Moore

🎧 Enjoying Athletes of the Reef? And the research? If you’d like to support the science behind it, tax-deductible donations make a real difference for our #shark & #coralreef fish #conservation research. Funding is tough right now. Every bit helps. 🦈🌊 rummerlab.com/donations #RummerLab #physioshark

Just out! @conphysjournal.bsky.social led by new PhD Dr José Trujillo w/ @physioshark - warmer waters (thermal sweet-spot) increased acceleration, agility, & response time in newborn blacktip reef sharks 🦈 📄 academic.oup.com/conphys/arti... @universityofotago.bsky.social @jcuofficial.bsky.social

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

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

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

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

🦈 New paper in Ecology & Evolution 📑 via our Physioshark research (ongoing since 2013 in French Polynesia🌺)! Fisheries catch data can be used to unravel elasmobranch aggregation dynamics, social structures, & group behaviours. Case study: newborn blacktip reef sharks. 🔗 doi.org/10.1002/ece3...

New potential shark nursery - part of @physioshark research, ongoing annually since 2013. How many baby blacktip reef sharks can you count?🦈 Protecting them means safeguarding the future of these incredible predators & the reefs they support! 🩵💚💙 🎞️ by @orianeservant www.instagram.com/reel/DGPhmC2...

What’s your take? One of our most provocative topics in “evidence & controversy in marine science” - shark mitigation issues in Australia and worldwide - expertly presented by @sawsharkman.bsky.social  Thank you Dr Raoult! 🫶🏼🦈

Do you like sharks? 🦈 They can range in size from 🤏🏼 20cm to 📏20m & all kinds of shapes! Join us for Joel Gayford’s PhD confirmation seminar at JCU or DM for zoom link. “From ocean miniatures to ocean giants: the evolution of body size & body form in Chondrichthyes” #sharks #evolution #morphology
