Characteristics (Original description in French) The body is depressed and oval. The dorsal surface is covered with a villous or papillose texture. The rhinophores (sensory organs) are retractile into a lobed cavity. The head is large and veliform (sail-like), bearing short, lobiform tentacles. The gill apparatus is composed of tripinnate leaflets arranged in a circular pattern.
The labial armature (jaw) is composed of small hooks. The radula lacks a central tooth; instead, it features one very large, hook-shaped lateral tooth and a few smaller marginal teeth.
