Description
Slipper lobsters are instantly recognisable by their enlarged violet coloured antennae, which project forward from the head as smooth wide plates. The brownish-red body is typically flat and robust and is covered with granulous bumps and fine hairs and the first abdominal segment has red streaks. The feet, all without claws, end with pointed nails and the first pair are shorter and more robust than the others.

Biology
Reproduction takes place in the spring. The slipper lobster is considered to be an endangered species.
