Rhino rays - the 16 species of wedgefishes and giant guitarfishes - are the most threatened marine taxa in the world. Population declines around the world have led to all but one species to be listed as Critically Endangered on the IUCN Red List of Threatened Species. These declines are largely due to fishing pressure but also because these species have some of the highest value fins. In 2019, all species were listed on CITES Appendix II which requires that their trade is regulated through a permitting system. To support with species and fin identification, the Wildlife Conservation Society and Elasmo Project developed a guide to these species. It is available in English and French and can be downloaded for free.
