The cap-shaped profile is not as pointed as the similar Capulus ungaricus. The shell has hardly more than one whorl. The oval-shaped aperture covers approximately 90 percent of the shell length.


The smooth velutina is often found under rocks on sandy or rocky substrate. It is often seen on sea squirts laying its eggs in them so they can suck nutrition from the body fluid of its host. It has a wide depth range from the subtidal zone to 1000 meters.


It is widespread in the North-East Atlantic Ocean as far south as the Mediterranean, as well as in the northern Pacific Ocean.
