Like many other small crabs, the long legged spider crab is a master of disguise. With algae attached on its very thin legs, they are easily confused with the stems of small seaweed. The pear-shaped carapace never exceeds a length of 28 mm. Sometimes you can find it trying to cover the body by pulling a seaweed over itself.


You may encounter it on any diveable depth. It rarely goes deeper than 50 meters, but has been reported on 350. It seems to prefer locations with muddy sand.


It is registered in the Mediterranean and East Atlantic Ocean, from the Azores to Nordland, Norway.
