}} The velvet crab is alternately velvet swimming crab, devil crab or lady crab, Necora puber, is a species of crab. It is the largest of the swimming crab family (Portunidae) found in British coastal waters. It has a carapace width of up to {{convert|100|mm}}, and is the only species in the genus Necora.[1] Its body is coated with short hairs, giving the animal a velvety texture, hence the common name. It is one of the major crab species for United Kingdom fisheries, in spite of its relatively small size. The velvet crab lives from southern Norway to Western Sahara in the North Sea and in north Atlantic as well as in western parts of the Mediterranean Sea, on the rocky bottom from the shoreline to a depth of about {{convert|65|m}}. The last pair of pereiopods are flattened to facilitate swimming. References1. ^{{cite journal |author=L. B.
