Thalassoplanes is a genus of sea snails, marine gastropod mollusks in the subfamily Parancistrolepidinae of the family Buccinidae, the true whelks.[1]
(Original description) The shell is short, with a very short siphonal canal. The operculum is straight, elongate, and wedge-shaped, its extreme apex slightly deflected to the right. The radula, typical for the group, has a formula of 1/6 + 1/0 + 1/6, with an obsolete rhachidian cusp.
The animal is blind; the male possesses a small, subcylindrical verge, lacking appendages.[2]
