What is the symbiotic relationship between sea cucumbers and crabs and shrimp?

Sea cucumbers often share a symbiotic relationship with crabs and shrimp, particularly in terms of habitat and protection. Crabs and shrimp can be found living on or around sea cucumbers, benefiting from the shelter they provide from predators. In return, these small crustaceans help keep the sea cucumbers clean by feeding on parasites and debris on their surface. This mutualism enhances the survival and health of both parties involved.
