Cleaner shrimp

From Wikipedia, the free encyclopedia

Cleaner shrimp is a generic term for any swimming decapod crustacean that cleans other organisms of parasites. This is a widely-cited example of symbiosis: a relationship in which both parties benefit. The fish benefit by having parasites removed from them, and the shrimp gain the nutritional value of the parasites. In many coral reefs, cleaner shrimp congregate at cleaning stations.

Cleaner shrimp may belong to any of three families, Palaemonidae (including the spotted cleaner shrimp, Periclimenes yucatanicus), Hippolytidae (including the Pacific cleaner shrimp, Lysmata amboinensis) and Stenopodidae (including the banded coral shrimp, Stenopus hispidus[1]. The last of these families is more closely related to lobsters and crabs than it is to the remaining families. The term "cleaner shrimp" is sometimes used more specifically for the family Hippo of the genus Lysma.

Cleaner shrimp are often included in salt water aquaria to keep the tank clean.
