Description

Shell

The shell of Marginella gemmula, while glossy and smooth to the touch, has spires that can be anywhere from flat to moderately elevated. Most shells have various colors, but a small number can be colorless. On the outside of the shell, the columella has four plaits. The outside lip is thicker than other such creatures, and the inside of the shell sports a denticulate set of teeth and/or folds. Unlike other gastropods, Marginella gemmula's siphonal canal is not very deep, but is still present. There is no operculum present with Marginella gemmula.

Flesh

The head of Marginella gemmula is bifurcated, with the siphon extending behind it. When moving, the foot of the animal extends past the shell.
