mutualism
Spider crabs have a symbiotic relationship with algae because they use the algae for camouflage. The algae attaches to the spider crab's shell, providing it with a protective covering that helps it blend in with its surroundings and avoid predators. In return, the spider crab provides the algae with mobility and access to nutrients as it moves around the ocean floor.

hermit crabs
commensalism

yes it does
No. Hermit crabs and sea anemones have a symbiotic relationship that is not the typical prey/predator relationship of most organisms.
Crabs and leeches have a parasitic relationship in their natural habitat. Leeches attach themselves to crabs and feed on their blood, which can weaken the crab and make it more vulnerable to predators.
