Hydrogenisina

Hydrogenisina is a genus of sea snails, marine gastropod mollusks in the family Clathurellidae. The genus was described by Powell (1942).

Hydrogenisina comprises several species, most of which are marine snails that inhabit rocky shores and shallow coastal waters. These snails are characterized by their small to moderate size and elongated, tapering shells with a visible umbilicus.

The shells of hydrogenisina snails are typically smooth, translucent to bluish-grey in color, and ornamented with a fine reticulated pattern. The spire is conical to globose, with a broadly rounded apex. The suture is very oblique.

Species within the genus are found in tropical and subtropical regions around the world, with some occurrences in temperate waters. Hydrogenisina snails are primarily carnivorous, feeding on various invertebrates and small crustaceans.

Some species of hydrogenisina are known to be associated with specific types of coral reefs or rocky substrate. Research on this genus is still in its early stages, and more study is needed to understand its ecological and evolutionary roles.

Hydrogenisina is occasionally encountered in the collection of deep-sea and shallow-water specimens. More research is necessary to assess the potential of these snails as bioindicators or other indicators of ecosystem health.
