Decorator Crab

By plucking algae, anemones, and sponges from the surrounding environment and sticking it on its body, the decorator crab is a resourceful artist. About 75 percent of decorator crabs (also known as Majoid crabs) participate in some type of shell decoration. A fine bristle of hairs along their body act like Velcro and latch on to the chosen decorations.  But the adornments are more than a fashion-forward style—scientists believe the decorated shells help protect the crabs from predators. A halo of stinging anemones would be quite the deterrent for a hungry fish. They also may help as a type of camouflage.
