One of the more interesting behaviours that divers can encounter underwater is the always entertaining relationship between a cleaner shrimp and the creature that is being cleaned. It might look like the shrimp is an easy meal for a moray eel as it prances along the morays head but in fact the moray more than tolerates the shrimps presence as it picks parasites from its skin and gums. I always enjoy watching the “fearsome” moray flinch when the shrimp grabs a particularly sensitive piece of skin from the eel. The observant diver can witness all kinds of cleaning behaviour on the reef at all times of day. Shrimp are one of the more active cleaners but many species of small fish such as wrasse and butterfly fish are also commonly found cleaning other denizens of the reef. Although it is common to see most fish visit a cleaning station from time to time, perhaps the most common visitors to these “clinics” seem to be moray eels. In this photo, a yellow margined moray eel is being cleaned by a scarlet lady cleaner shrimp beneath a small coral head at the Seraya Secrets dive site in NE Bali, Indonesia.
