The IUCN also lists nine mollusc subspecies as endangered.

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.

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]
The endangered marine snail with a coveted iridescent shell remains threatened by a disease called withering syndrome, which it may be more susceptible to due to the stress of ocean warming and ...
The estimate of 85,000 mollusks includes 24,000 described species of terrestrial gastropods. [9] 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 ...
