Genus
Common name: Fireworm
Scientific name: Eurythoe
Eurythoe is a genus of polychaete worms commonly known as fireworms. These segmented worms are known for their potent bristles that can cause irritation when handled. They are often found in reef aquariums, where they can be both beneficial and problematic. They help with detritus breakdown but can also prey on small invertebrates or corals. Identification is key, as not all bristle worms are harmful, and some species of Eurythoe can be reef-safe.
