Shield-limpets are commonly encountered under rocks. A Shield-limpet is often mistaken for a slug because its shell is much smaller than its body. Its body usually folds up around the edges of the shell and may cover most of the shell. They come in various colours. Their body may be black or beige, and shell white or brown.

Why Shield-limpet? 'Scutus' comes from the word 'suctum' which is the name of the Roman shield which the shell resembles. Shield-limpets belong to Family Fissurellidae which includes some limpets with a hole at the top of the shell. Shield-limpets, however, don't have a hole at the top of its shell.

Shield-limpet food: Most Shield-limpets graze on algae.
