Amphipods: Amphipoda

Seventy-one species of amphipods are listed by the World Conservation Union (IUCN). Two species are listed as Extinct, or no longer in existence; seven as Critically Endangered, facing extremely high risk of extinction in the wild; six as Endangered or facing a very high risk of extinction in the wild; and fifty-six as Vulnerable or facing high risk of extinction in the wild. Nearly all of these are freshwater species found in caves or underground springs. The parasitic species of dolphins, porpoises, and whales are not listed, even though many of their hosts may be considered threatened or endangered.
