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.
The white abalone, scientific name Haliotis sorenseni, is a species of large sea snail, a marine gastropod mollusk in the family Haliotidae, the abalone. [3]The white abalone is an endangered species in the United States; it may now have the smallest population of all eight of the abalone species on the west coast of North America.
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.
Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of September 2016, the International Union for Conservation of Nature (IUCN) listed 581 critically endangered mollusc species, including 117 which are tagged as possibly extinct. [1] [2] Of all evaluated mollusc species, 8.0% are listed as critically ...
The number of Mexico’s critically endangered vaquita marina porpoises sighted in the Gulf of California fell to between 6 and 8 this year, researchers said Tuesday. Last year, experts on a ...
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.
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 ...
There are 34 freshwater gastropod taxa on this list. The only marine endangered gastropod is Haliotis sorenseni. The only overseas endangered land snail is Papustyla pulcherrima. Altogether 36 gastropod species are federally listed as of 2 October 2009. [4]
