Scutus is a genus of large sea snails or limpets with the common name "shield shells". These are marine gastropod molluscs in the family Fissurellidae, the keyhole limpets and slit limpets.

Both the common name and the scientific name reflect the fact that the shells of species in this genus resemble a Roman shield.

Description

The animal itself has a large black mantle which usually completely covers the shell, giving the animal a superficially slug-like appearance.
