The final chapter of my PhD is published in Journal of Experimental Biology! And, we got the cover! We used biologgers to estimate great hammerheads' temperature “sweet spot.” We saw they can perform well at a range of temps, which supports observations from the field. (1/2) 🌊🦑🧪🐟

New paper out today! Using accelerometers to generate thermal performance curves in great hammerhead sharks. Their low activation energies may explain why they can perform well across seasons.

New paper introducing the term of SUPER HABITAT for sharks in which all critical activities (resting, feeding, mating & giving birth) occurs. 🦈🌴❤️🍽️ 👶 Access the paper here: www.sciencedirect.com/science/arti... @dr-yannis.bsky.social @charlie-huveneers.bsky.social

‼️ New important shark paper 🦈 We demonstrate that all critical life stages (resting, feeding, being cleaned, mating & giving birth) can occur in the small Fakarava channel & we define it as a “super habitat” www.sciencedirect.com/science/arti... @dr-yannis.bsky.social @charlie-huveneers.bsky.social

Further coverage, this time from National Geographic, of new paper by @dr-yannis.bsky.social discussing #electricrays using their shocks to avoid getting eaten by large sharks www.nationalgeographic.com/animals/arti...

This animal has a built-in taser to stun sharks

Electric rays are staying out of the stomachs of sharks by shocking them—with up to 200 volts.

Popular press coverage, from phys.org, of the new paper by @fiu.bsky.social researcher @dr-yannis.bsky.social that explains how electric rays escape #shark predators by zapping them with an electric⚡ shock!!! 😮

This was a HUGE effort with LOTS of field time and LOTS of analysis – huge thank you to all my coauthors and the many folks who contributed in the field. Very proud of this one. (4/4) @dr-yannis.bsky.social 🦑🧪🌊🐟 See the paper: link.springer.com/article/10.1...

Energetic benefits of prey choice for a shark-eating shark - Oecologia

Optimal foraging theory has been used to understand the foraging choices of animals but is rarely applied to large predatory fishes due to difficulties measuring their behavior in the wild. Great hamm...

New paper lead by @etspencer.bsky.social We use biologging to understand why great hammerheads may specialize on large prey like other sharks. If they hunt blacktips off south Florida then they probably only have to catch a shark once per month link.springer.com/journal/442

Update from @dr-yannis.bsky.social on sharks on artificial reefs

Very sad to hear the great David Lynch has passed away. He leaves a number of great films particularly the elephant man, and blue velvet. He also gave us the incredibly influential tv series Twin Peaks variety.com/2025/film/ne...

Director David Lynch, who radicalized American film with with a dark, surrealistic artistic vision in films like 'Blue Velvet,' has died. He was 78.

Florida is a place where we are used to living amongst large reptiles!

This is the first paper that I publish with undergrads from a statistical consulting & collaboration course I teach at University of Toronto. With TA help, they did an amazing job fitting hidden Markov models and learning about Goliath Grouper. Our undergrads are top notch 👌🏽 #AnimalMovement 🧪
