Decorator crabs are a diverse group of brachyuran crabs they have the unusual habit of “decorating” their carapace with bits of algae and invertebrates. In order to accomplish this, they attach these materials to specialised hooked setae on their carapace that hold decorations in place much in the same way that velcro latches onto fabric making them perhaps nature’s most fashion-conscious animal. But while we humans adorn ourselves to be noticed, crabs do it for the opposite reason: the decorations often provide camouflage against predators. Against the proper background, a decorator crab can blend in perfectly. Suitable for Reef Aquariums.
