Identifying features:  The Decorator Crab is the most spidery of all the intertidal spider crabs, and has long and slender legs. This crab has quite an amazing adaptation for camouflage: it has sharp spines all over its body that allow it to actively decorate itself with things such as bits of seaweed, little pieces of sponge and any thing else in their environment that makes them blend in.
