Two-thirds of all species of freshwater crabs may be at risk of extinction, according to a recent study. The International Union for Conservation of Nature (IUCN) Red List assessment, produced by scientists from the Zoological Society of London and Northern Michigan University, found that all 1280 known freshwater crab species are at risk while one in six species have an “elevated risk of extinction.” Those in Southeast Asia are most vulnerable.
