It may be confused with the more slender common spider crab. The most distinct difference is the short, splitted rostrum, in contrast to the longer, single-pointed rostrum of the common spider crab. If the carapace is not covered by sponges, you might notice a transverse row of four spines, right behind the eyes. The egg-shaped carapace narrows towards the front and may reach a length of 35 mm. The legs are very long, relative to the modest body size.


As many other crabs, it is not choosy on the substrate. You may find it on rocky, sand as well as muddy substrate. It is most frequent on a depth range from 4 to 180 meters.


It is widespread along the east coasts of the Atlantic Ocean, both in Europe and Africa, as well as in the Mediterranean, the Black Sea and even the Seychelles.
