Amphinomidae, also known as the fireworms, bristle worms or sea mice, [2] are a family of marine polychaetes, many species of which bear chaetae mineralized with carbonate. [3] The best-known amphinomids are the fireworms, which can cause great pain if their toxin-coated chaetae are touched or trodden on. [4] Their relationship to other polychaete groups is somewhat poorly resolved. [4]
Complanine is a quaternary ammonium salt that has been isolated from the marine fireworm Eurythoe complanata . It causes an inflammatory effect upon contact with the skin or mucous membranes.
It was previously known that handling the fireworm caused it to release a chemical that induces inflammation of the skin of marine predators and mammals (including humans). Complanine was the first compound isolated from the fireworm which causes these effects. [5] [6] It is presumed that this compound's function is to deter predators of the fireworm.
Most genera in Amphinomidae are divided into two subfamilies: Amphinominae, and Archinominae. [7] [a]
