Description

edit

The pink-lipped topshell has monomorphic purplish-black shell with a crimson inner lip.[4] The shell in adults is between 18 mm and 51 mm.

Distribution

edit

This marine species occurs from False Bay to South Transkei near the Mbashe River, South Africa.[5][6]

Ecology

edit

Especially small individuals of this species that live in the intertidal zone are predated upon by rock lobsters. Larger individuals largely escape this predator by migrating to deeper waters, where they find a size refuge.[5]
