Corallimorph Decorator Crab - Cyclocoeloma tuberculata

The Corallimorph Decorator Crab - Cyclocoeloma tuberculata are usually seen at night time when they come out to feeds. They decorate their carapace with pieces of corals, mostly Corralimorph, hence their name. But they have been noted to also decorate themselves with other types of soft corals.

In the picture, they are dull grey in colour, the greenish and purple stuff are the corals they have attached to their carapace.
