Under rocks on exposed rocky shores
Decorator Crabs have a distinctive pointed body shape – round at the bottom with a pair of spikes at the front. They are covered with gold-brown hairs.  Body width to 40 mm

These hard to find crabs create camouflaging gardens on their bodies from either seaweeds or encrusting animals such as bryozoans or sponges. They are scavengers.
