Description edit

The shell size of Euthria cornea varies between 20 mm and 80 mm.[2] 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.[4]

Distribution and habitat edit

This species occurs in the Atlantic Ocean off Portugal and Morocco and in the Mediterranean Sea.[2] It can be found at depths of 5 to 30 m, mainly on rocky substrates.[4]
