Give me a symbiotic relationship of two marine organisms.

An example of a symbiotic relationship between two marine organisms is the relationship between the cleaner shrimp (such as Lysmata amboinensis) and the marine fish (such as gobies).

The cleaner shrimp sets up cleaning stations in coral reefs, where they perform a cleaning service by removing parasites, dead skin, and other debris from various fish species. The cleaner shrimp benefit from this relationship as they gain a food source while providing cleaning services.

The fish, on the other hand, benefit from this relationship as the cleaner shrimp remove parasites that may harm them. The fish also use specific signals or movements to indicate that they are ready to be cleaned, which the cleaner shrimp respond to.

Overall, this symbiotic relationship is beneficial for both the cleaner shrimp and the fish, as it helps maintain their health and well-being in the marine ecosystem.
