Etymology: "Fireworms" is the plural of "fireworm," a compound of "fire" and "worm." The name refers to the marine bristleworms of the family Amphinomidae, whose bristles can cause a burning sting when touched, and to bioluminescent sea worms that glow when disturbed. Here the "fire" points to the sensation of heat or burning rather than to flames, so the name describes what happens when the animal is handled. Both parts of the compound are old native English words. "Fire" comes from Old English "fēr," and "worm" from Old English "wyrm," which in earlier usage could mean any small creeping creature, including snakes and grubs. Joining them produced a descriptive name, one of many English compounds that label an animal by a striking trait.

Synonyms: bristle worms, polychaetes, annelids
