Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 507 endangered mollusc species. [1] Of all evaluated mollusc species, 7.0% are listed as endangered. The IUCN also lists nine mollusc subspecies as endangered.
Gastropods [ edit ] There are 267 extinct species, 134 possibly extinct species, 14 extinct in the wild species, two possibly extinct in the wild species, five extinct subspecies, one possibly extinct subspecies, and five extinct in the wild subspecies of gastropod evaluated by the IUCN.
Haliotis cracherodii, the black abalone, is a species of large edible sea snail, a marine gastropod mollusk in the family Haliotidae, the abalone. [3]This species is relatively small compared with most of the other abalone species from the eastern Pacific, and it has a relatively smooth dark shell.

This endangered cetacean is not only the smallest porpoise species, but the most rare. Where there were once thousands of vaquitas swimming in the sea, today there may only be about 10 individuals ...
Different estimates for aquatic gastropods (based on different sources) give about 30,000 species of marine gastropods, and about 5,000 species of freshwater and brackish gastropods. Many deep-sea species remain to be discovered, as only 0.0001% of the deep-sea floor has been studied biologically.
