Oregonia gracilis, commonly known as the graceful decorator crab, is a species of crab belonging to the family Oregoniidae.[3] Like other decorator crabs it habitually attaches other organisms to its back.[4] The sessile organisms are attached to hooked setae that act as a sort of velcro attachment. This decoration provides visual and chemical camouflage thus reducing predation risk.[5] Pacific halibut are a major predator of O. gracilis. Other predators include octopus and sea otters. The main food source of O. gracilis is floating kelp and algae that they capture utilizing a waiting strategy in order to maintain cryptosis.[6]
