Hendrina

Hendrina is a genus of small, aquatic, carnivorous snails, marine gastropod mollusks in the family Pyramidellidae. The scientific name of the genus was first published in 1904 by the German malacologist Friedrich Hermann Loew. The genus is named after the type species, Hendrina hendersoni, which was described by Loew in the same publication.

Hendrina species are characterized by their small size, typically ranging from 1 to 2 millimeters in length. They have a conical shell with a smooth surface and a distinct protoconch. The aperture of the shell is oval and surrounded by a thin, white lip. The radula of Hendrina species is composed of small, chitinous teeth that are used for feeding.

Hendrina snails are found in shallow marine waters, typically in the intertidal zone. They are carnivorous, feeding on small invertebrates such as copepods and other small crustaceans. The reproductive biology of Hendrina species is not well understood, but it is believed that they reproduce sexually.

Hendrina is a small genus with only a few described species. The taxonomy of the genus is still under study, and new species may be discovered in the future. The genus is of interest to malacologists and marine biologists due to its unique morphology and ecology.
