Atys densus is a species of small tropical sea snail, a bubble snail, a marine opisthobranch gastropod mollusk in the family Haminoeidae, the haminoea bubble snails.[1]

Description

(Original description) The shell is small, oval, and thick, with a dirty white appearance. The surface is finely plicated and strongly striated in a transverse direction. Within the interstices, finer lines become visible when viewed under a lens. The aperture is narrow above but opens wide below. The outer lip is regularly arched; it is produced posteriorly, while anteriorly it is both twisted and produced, which allows it to partly cover the umbilicus.[2][3]

Distribution

This marine species is endemic to Australia and occurs in the Torres Strait and off Queensland.
