Cranial morphology in Mollisquama sp. (Squaliformes; Dalatiidae) and patterns of cranial evolution in dalatiid sharks [PDF]

Citizen Science for Sharks and Rays: Evaluating iNaturalist Records to Document Elasmobranch Diversity and Occurrence in the Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Elasmobranchs in the Mediterranean Sea face intense human‐induced pressures, with nearly half of their populations at risk of extinction. Overexploitation, limited data availability, lack of international cooperation and uneven public awareness hinder effective management.
