Spiral velvet snail:
Spiral velvet snail (Velutina velutina): Velutina velutina is distinguished from Smooth velvet shell (Velutina prolongata) by the opening, which is about as wide as it is long, whereas in V. prolongata, it is considerably longer than wide. Also, the periostracum clearly creates ridges on the shell, and a rougher outlook on the whole. when alive, Velutina velutina has a large white mantle with a clearly yellow edge around it.

This species usually feeds on tunicates, such as Sea Blisters (Ascidia callosa).
