Comprehensive Description

Biology/Natural History: Feeds on sponges, including Halichondria panicea, Myxilla incrustans, and Higginsia sp. According to Baltzley et al.,, many gastropods, including this species, have a special network of pedal ganglia in their foot which assists in crawling. The two main neurons involved produce pedal peptides which elicit an increase in the rate of beating of cilia on the foot, resulting in crawling.
