TL;DR: In this article, the authors present the first systematic analysis of threat for a globally distributed lineage of 1,041 chondrichthyan fishes (sharks, rays, and chimaeras).

TL;DR: Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.

TL;DR: The IUCN Shark Specialist Group has compiled a Global Status Report for Chondrichthyan Fishes (the Sharks, Rays and Chimaeras), with Red List assessments for over 100 species and regional reports on the status of shark fisheries, together with information on taxonomy; life history; trade; socio-economics; threats; and conservation and management initiatives as mentioned in this paper.

TL;DR: Overall chondrichthyan extinction risk is substantially higher for sharks, rays, and chimaeras than for most other vertebrates, and only one-third of species are considered safe.

TL;DR: The third report in the series of Mediterranean Red List Assessments presents the findings of an expert workshop at which 71 Mediterranean species of sharks, rays and chimaeras (cartilaginous fishes) were assessed using the IUCN Red List categories and criteria as discussed by the authors.
