Alaba (gastropod) explained

Alaba is a genus of sea snails, marine gastropod mollusks in the family Litiopidae.

Description

(Original description) The elongated shell is turreted. It is smooth and semi-translucent, with whorls that occasionally feature a few irregular varices. They often have fine axial ribs or striations. The outer lip is thin and simple, while the ovate aperture is slightly emarginate at the anterior end.^[1]

Distribution

Alaba is a cosmopolitan genus, but mostly distributed in shallow tropical and subtropical seas in coral reefs, rocky substrates, and seagrass beds.^[2]
