A new analysis published today in the journal Current Biology finds that one-third of the world’s chondrichthyan fishes – sharks, rays, and chimaeras – are now threatened with extinction according to International Union for Conservation of Nature (IUCN) Red List criteria.
In this new global analysis, experts assessed 1,199 shark, ray, and chimaera species against International Union for Conservation of Nature (IUCN) Red List criteria and found 391 (32%) qualify as Critically Endangered, Endangered, or Vulnerable. Species classified in these three IUCN categories are considered threatened with extinction. That statistic increases to more than one-third (37.5%) if Data Deficient species are assumed to be threatened in the same proportion as assessed species.
