Babella

Babella is a genus of very small sea snails, pyramidellid gastropod mollusks or micromollusks in the family Pyramidellidae within the tribe Chrysallidini (sensu taxonomy by Bouchet & Roctroi, 2005).

Description
The shell shows strong axial ribs between the sutures and three spiral keels, two of which are at the periphery, which falls in the deep sulcus between them, and one a little anterior to the middle of the base.

Distribution
The genus seems to be limited to tropical and temperate regions of the Pacific Ocean.

Life habits
Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are ectoparasites.
