The fireworm (Eurythoe complanata) belongs to the amphinomidae family, of the polychaete superclass. With a worldwide distribution, this polychaete is a common fixture beneath intertidal boulders and coral heads in tropical marine waters (Barroso et al, 2010). Bearing the highly distinguishable and painfal chaetae, these calcareous, harpoon-like tufts, extend from their parapodia. Harboring a mild, yet irritating neurotoxin many a diver and marine animal have had regrettable close encounters with this animal. The amphinomidae family is broadly categorised as a carnivorous, however, the preferred food sources are largely unknown. Bearing a relatively simplistic jaw structure, the E complanata utilises eversable mouthparts and well developed nuchal (chemosensory) organs to seek and aquire the quarry of their choice. A truly remarkable and unique animal, this web page will attempt to describe the day-to-day living of the E. complanata.
