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.
Scaly-foot gastropod Chrysomallon squamiferum, common name the scaly-foot gastropod, is a species of deep-sea hydrothermal-vent snail, a marine gastropod mollusc in the family Peltospiridae. This vent-endemic gastropod is known only from deep-sea hydrothermal vents in the Indian Ocean, where it has been found at depths of about 2,400–2,800 m ...
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.
This list of gastropods described in 2017 is a list of new taxa of snails and slugs of every kind that have been described (following the rules of the ICZN) during the year 2017. The list only includes taxa at the rank of genus or species. For changes in taxonomy above the level of genus, see Changes in the taxonomy of gastropods since 2005.
Muricidae is a large and varied taxonomic family of small to large predatory sea snails, marine gastropod mollusks, commonly known as murex snails or rock snails. With over 1,700 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized.
Haliotis cracherodii, the black abalone, is a species of large edible sea snail, a marine gastropod mollusk in the family Haliotidae, the abalone. [4]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.
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 ...
Monetaria moneta, common name the money cowrie, is a species of small sea snail, a marine gastropod mollusk in the family Cypraeidae, the cowries. [1]This species is called "money cowrie" because the shells were historically widely used in many Pacific and Indian Ocean countries as shell money before coinage was in common usage.
