Lepetodrilidae

Lepetodrilidae is a family of small, deep-sea sea snails, hydrothermal vent limpets, marine gastropod mollusks in the clade Vetigastropoda (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[2]

Description

These deep-sea species are found and are endemic at hydrothermal vents. Their limpet-shaped shell consist of non-nacreous aragonite. The thick periostracum covers the shell edge. The apex is posterior, in some species projecting posteriorly, and deflected to the right. The shell has no sculpture or it consists of beads or imbricate radial ribs. There is no operculum. The muscle scar forms the shape of a horseshoe. The rhipidoglossate radula is special as the lateral teeth descend toward the rachidian in a v-arrangement. The conspicuous penis is situated near the base of the right cephalic tentacle.[3]

Genera

Genera within the family Lepetodrilidae include:

gollark: Very efficient.
gollark: We have advanced processing units built out of magnetic monopole matter and manipulation of the structure of space-time.
gollark: Ours are kept in stellar plasma, actually.
gollark: I have 3GB of search indices and they don't even allow rapid search through memetic hazards.
gollark: Anyway, I need semantic search over memes quite badly. Also my paper archive.
