Lottia Alveus
''Lottia alveus'', the eelgrass limpet or bowl limpet, was a species of sea snail or small limpet, a marine gastropod mollusk in the family Lottiidae, the ''Lottia'' limpets, a genus of true limpets. This species lived in the western Atlantic Ocean. The eelgrass limpet now appears to be totally extinct, but up until the late 1920s, this species was apparently quite common, and was easy to find at low tide in eelgrass beds, in many sheltered localities on the northeastern seaboard of North America. Distribution before extinction This limpet was found from Labrador, Canada, as far south as New York. It may have become extinct as much as 60 years before its extinction was noticed. (Fall, 2005) Habitat This small limpet used to live on the blades of ''Zostera marina'', a species of seagrass. Cause of extinction The extinction of ''Lottia alveus'' does not seem to have been caused directly by human interference. This small limpet disappeared from the fauna because of a sudden cata ...

Limpet
Limpets are a group of aquatic snails that exhibit a conical shell shape (patelliform) and a strong, muscular foot. Limpets are members of the class Gastropoda, but are polyphyletic, meaning the various groups called "limpets" descended independently from different ancestral gastropods. This general category of conical shell is known as "patelliform" (dish-shaped). All members of the large and ancient marine clade Patellogastropoda are limpets. Within that clade, the members of the Patellidae family in particular are often referred to as "true limpets". Other groups, not in the same family, are also called limpets of one type or another, due to the similarity of their shells' shape. Examples include the Fissurellidae ("keyhole limpet") family, which is part of the Vetigastropoda clade (many other members of the Vetigastropoda do not have the morphology of limpets) and the Siphonariidae ("false limpets"), which use a siphon to pump water over their gills.
