Emperor shrimp (Periclimenes imperator) on the skin of a sea cucumber. The emperor shrimp hitches rides on larger animals for protection from predators. It usually chooses poisonous or inedible hosts. The host is not harmed by the shrimp, nor does it derive any benefit from carrying it. This type of relationship is called commensalism, a type of symbiosis. Photographed in Malaysia.
