Like other members of the Anthuridae, C. carinata has an elongated body, with the pereon somites being longer than wide. The eyes are small in comparison with Anthura gracilis. The first pereopods are broad and subchelate, the pleon segments are fused, and the pleotelson, which has a pair of statocysts, narrows to a rounded point. Between 14 and 27 mm, the species is a whitish colour with red-brown mottling.
Distribution and Habitat
Found around the coasts of England and Wales, especially in the south and west, with occasional records from western Scotland and southern Ireland. In or on the mud of estuaries and streams crossing the shore, most easily found at night when they crawl on the surface.
