[2] Eriphia verrucosa lives among stones and seaweeds in shallow water along rocky coastlines up to a depth of 15 metres (49 ft).

[3] It is reported to feed on bivalves, gastropods and hermit crabs,[6] or on molluscs and polychaetes.

[3] In the Black Sea, E. verrucosa is the only native species capable of breaking into the shells of the invasive snail Rapana venosa, although it is unlikely that it will present an effective biological control of the invader.

[3] The carapace is thick and smooth, ranging in colour from brownish-red to brownish-green, with yellow spots; its front margin is armed with seven "teeth" on either side, and five or six between the eyes.

In the springtime, E. verrucosa migrates to shallow water, less than 1 metre (3 ft 3 in) deep, and reproduction begins in May or June; the species is highly fecund.
