Atelecyclus rotundatus is a medium-sized crab found on the west coast of Europe and Africa as well as almost all the Mediterranean Sea and on the Cape Verde and Canary islands.[2] It has many common names, including circular crab, round crab and old man's face crab. It measures about 40 millimetres (1.6 in) across its almost circular, reddish-brown carapace and lives on coarse soft bottoms at shallow depths.[2] There are 9–11 sharp teeth on the front and 3 teeth between the eyes.[2]
This crab is sometimes mistaken for the more common Atelecyclus undecimdentatus. However, Atelecyclus undecimdentatus can be distinguished by its wider carapace and coarser granulations.[3]
