A landmark scientific workshop has identified 124 Important Shark and Ray Areas (ISRAs) across the European Atlantic, providing the first comprehensive map of critical habitats for threatened species such as Basking Shark, Tope, Spiny Dogfish, Sicklefin Devil Ray, and Angelshark.

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
