Eupleura sulcidentata
Eupleura sulcidentata, common name the sharp-ribbed drill, is a species of sea snail, a marine gastropod mollusk in the family Muricidae, the murex snails or rock snails.
Description
This is a small species, reaching only up to 25mm.Overall shape is that of a fairly typical murex in miniature, though its varices are spaced at approximately 180° apart, rather than the ~120° more common in murexes. The varices have a wavy appearance and a sharp-looking edge. In-between the varices are smaller bumps or nodes. Color is usually whitish or off-white, occasionally buff or even brown. Sometimes a brown stripe is present on the upper part of each whorl.
The sharp-ribbed drill is a carnivore and, as the name "drill" implies, it bores holes into the shells of other mollusks using its radular teeth.
