Majestic in purple, a spotted cleaner shrimp in the waters off Bonaire Island in the Caribbean works hard for its customers. This cleaner shrimp (Periclimenes yucatanicus) associates with a sea anemone and attracts fish from which it cleans and eats detritus such as parasites and algae. Such a symbiotic relationship benefits both the shrimp and the fish.
