Emarginula crassa, the thick slit limpet, is a species of sea snail, a marine gastropod mollusk in the family Fissurellidae, the keyhole limpets. [1]
The thick slit limpet is a large keyhole limpet with a length of 30 mm and about 15 mm high. The white shell is cap-like with a reticulate sculpture. The apex is curved backwards. The radial ribs number about 50 and are less pronounced than in other species of this genus. There is an exhalant slit in the anterior margin.
This species is found on hard surfaces, usually under stones, from low water levels to the sublittoral zone at depths up to 200 m. It occurs in European waters from Norway, Orkney and Shetland, south to the British Isles.
This limpet is deposit feeder and a grazer.
Fissurellidae, common name the keyhole limpets and slit limpets, is a taxonomic family of limpet-like sea snails, marine gastropod molluscs in the clade Vetigastropoda. Their common name derives from the small hole in the apex of their cone-like shells. Although superficially resembling "true" limpets, they are in fact not closely related to them.
