Life stage-specific habitat use and trophic ecology of the critically endangered great hammerhead (Sphyrna mokarran) - Reviews in Fish Biology and Fisheries
The great hammerhead (Sphyrna mokarran) is listed as Critically Endangered by the IUCN Red List and is one of the most iconic shark species worldwide. Despite its emblematic status, there are major…

‼️ 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”

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!

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

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 🧪
