commensalism
Barnacles on a crab's shell improve its toughness, while the barnacles (normally lacking motility) are able to visit more than one location to obtain food, and may even feed on the crab's prey. Some barnacles, however, can cause damage or sterility in some species of crabs.
They aren't symbiotic : the barnacles (crustaceans related to crabs) are parasites on the whale's skin, and will also attach to boats, docks, and other marine locations.
They won't have any shells to live in
one example are whales and barnacles, the barnacle benefits from the whale because it eats and gets protection, and the whale does not seem to be affected in any way.Commensalism is a symbiotic relationship where one party benefits and the other is not harmed. Examples of commensalism in the ocean are barnacles living on turtles, remoras feeding on a shark's food scraps and a crab that makes its home in an oyster's shell.
There is only one main difference between hermit crabs and barnacles. Hermit crabs have a hard exoskeleton that protects their bodies.
A sacculina is a genus of barnacles, which is a castrator of crabs.

Crabs do eat other crustaceans like barnacles, krill, shrimp and crayfish.
Crabs, hermit crabs, ghost shrimp, shrimp, barnacles, lobsters, isopods, amphipods.
No. Hermit crabs and sea anemones have a symbiotic relationship that is not the typical prey/predator relationship of most organisms.
