Description

The shell size of Euthria cornea varies between 20 mm and 80 mm. This mollusk has a robust fusiform shell, with a sharp apex. The opening is oval, wide, with slight striae. The horny operculum is oval. The coloration of the shell is quite variable, with irregular dark spots on a brownish-gray background. The mollusk is orange. This predatory species mainly feeds on small bivalves, opening slightly the valves with the strong foot and sucking the tissues.

Distribution and habitat

This species occurs in the Atlantic Ocean off Portugal and Morocco and in the Mediterranean Sea. It can be found at depths of 5 to 30 m, mainly on rocky substrates.
