Read my review of John Long’s book The Secret History of Sharks in @currentbiology.bsky.social

A fascinating read about the deep history of sharks, the scientists who study them, and the adventures they have in the quest to learn more.

Recently, 124 Important Shark and Ray Areas (ISRAs) were delineated for the European Atlantic 🦈
This effort had data contributions from 214 researchers, including ETN members! Many of these ISRAs were partially/ompletely supported with telemetry data, underscoring the importance of this information.

Some awesome news for your Monday. Critically endangered grey nurse sharks are increasing in number by about 5% a year, the first time the conservation efforts have seemed to work for this species! Still just 1500 breeding adults across eastern Australia...

Huh.

New paper is officially out!
Ratfish have a second jaw on their foreheads - CT + histology show they’re real teeth, built from the same tissues and signals as oral teeth.

This common fish has an uncommon feature: forehead teeth, used for mating
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads,...
