Family Palaemonidae

The family Palaemonidae is a large family of decapod crustaceans, commonly referred to as commensal shrimps because many of them do live in commensal relationships with a wide variety of invertebrates. Currently over 950 species are recognized in 137 genera, but as new species are discovered on a regular basis this is just a ballpark figure.

The family includes a number of commercially important species, particularly the fresh and brackish water genus Macrobrachium. Several species clean fish of parasites and dead tissue. They typically advertize their presence by long white antennae which they wave, apparently to draw attention to their services. Along with the various cleanerfish this provides an important service to the coral reef ecosystem. In the Caribbean Pedersen's cleaner shrimp can often be seen in action cleaning green morays or cods with apparent impunity. Some palaemonid species live on featherstars and take on the coloration of their host. Others live on antipatharian (black) corals where they blend almost perfectly with the coral polyps.
