Oregonia gracilis, The Graceful Decorator Crab tools used by the crabs to conceal themselves but these animals benefit from this relationship as well (Weis ). A specific anemone that has similar qualities to the ones that the graceful. Symbiotic relationships occur in both marine and land animals. The decorator crab snips off pieces of sponge and anemone to add to its shell. Using the same ideology as the clownfish, the decorator crab is known for its relationship with sponges and anemones. These crabs gather.
Barnacles are filter-feeders, relying on plankton that they filter through feather-like appendages that extend through holes in their shells. An added benefit is protection from predators, as only the most courageous of predators is likely to attack a whale.Ant & aphid ... Symbiosis
For the most part, the whale remains unaffected—they can support the weight of thousands of barnacles at a time. Barnacles and whales are an example of a symbiotic relationship of commensalism.

The pistol shrimp spends its days digging small burrows in the sandy seafloor searching for food. By doing so, the pistol shrimp creates holes that are just the perfect size to provide a resting place and protective shelter for a goby. The pistol shrimp allows the goby access to the holes it digs—rent-free—as long as the goby completes one job in return: When a predatory fish approaches the goby flicks its tail several times, alerting the shrimp to the coming danger.
Both the goby and shrimp retreat deep into the burrow to wait out the attack. A decorator crab shows its style in the latest fashion.
5 Symbiotic marine relationships
The decorator crab snips off pieces of sponge and anemone to add to its shell, gaining a piece of camouflage in the case of a sea sponge or a handy weapon in the case of a poisonous anemone. The sea sponge and anemone both continue to live on the back of the decorator crab and, like a barnacle, gain the benefit of being transported to different feeding areas.

The striped fish can often be seen swimming below a shark as it cruises the sea in search of prey. Feeding and Commensalism Relationship Other than algae, the Graceful Decorator Crab's diets consists of plankton, small and dead animals, and have even been known to occasionally eat other crabs Larson. Using their long pincers, these omnivores are able to extract food from crevices and the sea floor or can simply take the food growing on their back Cattle Point. These powerful pincers are also able to crack hard shells like those of other crustaceans.

During the course of feeding, Oregonia gracilis often times drops morsels of food, in turn feeding and supporting other creatures around them. One such example would be anemones, which provide an important form of protection from many various predators.
A specific anemone that has similar qualities to the ones that the graceful decorator crab interacts with is the ritteri anemone. These crabs have even been observed picking up and waving the anemones stinging tentacles at oncoming predators Weis Predators Threats often encountered by Oregonia gracilis are fish, sea otterscephalopods such as the gaint pacific octopusand other various predacious animals.
Being a bottom dwelling fish in the crabs main habitat, pacific halibut is one of the Graceful Decorator Crab's most common foes. Both live in the cold, northern waters of the Pacific making encounters a common occurrence.
Another prevalent hazard encountered at the bottom of the ocean are cephalopods like octopi. Even other crabs have been known to attack and eat them making their choice in camouflage even more critical.
Parasitic Relationships While the crabs may spend their time worrying about halibut or cephalopods, there are other organisms which pose just as great, if not more of a threat to them; parasites. Some of the most common parasites found on crabs are rhizocephalans, a type of parasitic barnacle Weis
