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...

Incredible biomass of bigeye jacks at Malpelo Island, Colombia

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...

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

New paper! Electric rays can use their electric discharge to repel large sharks. Here a white shark carrying a camera approaches a Pacific electric ray. Something caused it to sprint 20 m shallower! onlinelibrary.wiley.com/doi/10.1111/...

New paper! We review how to use AI to analyze animal borne camera tag footage. Important with how large these datasets are getting! besjournals.onlinelibrary.wiley.com/doi/10.1111/...

New paper! We combine lab based respirometry and biologging to measure the vertical energy landscape of dolphin fish off Mexico and Japan. royalsocietypublishing.org/doi/10.1098/...

New paper! We use biologging to look at diel changes in search behavior by great hammerhead sharks, a predator that never stops swimming @etspencer.bsky.social www.sciencedirect.com/science/arti...

New paper on stingray activity patterns in Belize. There is lots of individual variability with regards what time of day rays are active, but all seem to be highly active in shallow water. These may represent important foraging habitats cdnsciencepub.com/doi/abs/10.1...

Farewell to the great Gene Hackman. Too many films to list but my favorites included the conversation, French Connection, and Mississippi Burning. One of the last of the great cinema tough guys apnews.com/article/gene...

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...

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 🧪

New paper! We use telemetry to identify behaviors of goliath grouper while they are in a seasonal spawning aggregation. Behaviors will vary based on lunar phase, water temperature and current strengths. www.int-res.com/abstracts/me...
