Head Shield Slugs [Cephalaspidae]

Description

Cephalaspidae, or Head Shield Slugs, are a family of marine gastropods distinguished by their unique head shield, a structure used to plow through the substrate and for protection. These gastropods lack an external shell in their adult form, showcasing their vibrant and varied colors. They inhabit a variety of marine environments, from shallow waters to the deep sea, and feed on detritus, algae, and sometimes small invertebrates. Their ability to contract their body into a shielded head is a notable defensive mechanism.
