The report and supplementary materials can be downloaded from the IUCN website.

The report documents that 13.5% of the region’s shark, skate, and chimaera species qualify for one of the three “threatened” categories — Critically Endangered, Endangered, Vulnerable — associated with an elevated risk of extinction.
