Acrilla acuminata is a species of sea snail, a marine gastropod mollusk in the family Epitoniidae, the wentletraps.[1]

Description

The elongated, acuminate shell is imperforate. The shell contains 15 whorls. These are barely protruding, and are surrounded in front by a thin keel. The sculpture shows very numerous, thin and curvilinear varicose threads. The oval aperture has a thin margin. The pale yellow shell shows on each whorl two bands, one pale near the suture, one broad, distinct in the middle of the whorls.[2]

Distribution

This marine species was found originally off Malacca, Malaysia. It also occurs off Taiwan, Korea, Japan and Australia.[3]
