The bearded fireworm (Hermodice carunculata) is a marine bristleworm that belongs to the family Amphinomidae. It is also commonly known as the bristle worm or fireworm. The species is found in tropical and subtropical waters of the Atlantic Ocean, including the Caribbean Sea.\n\nHere are some key characteristics of the bearded fireworm:\n\nAppearance: Bearded fireworms have elongated, segmented bodies that can reach lengths of up to 35 centimeters (14 inches). They are usually reddish-brown or pinkish in color and have numerous bristle-like appendages, known as setae, covering their body. The setae are used for defense and can cause a painful sting if touched.\n\nHabitat: These fireworms are primarily found in coral reef ecosystems, where they inhabit crevices, coral rubble, and other hiding places. They can also be found in seagrass beds and rocky areas.\n\nFeeding habits: Bearded fireworms are carnivorous and feed on a variety of organisms, including small invertebrates and carrion. They use their sharp jaws to capture prey and consume it with the help of their pharynx.\n\nDefense mechanism: The bristles or setae on the body of a bearded fireworm are a defensive adaptation. When disturbed or threatened, they can release these bristles, which have microscopic, venomous spines. These spines can cause painful stings and may even penetrate the skin, leading to inflammation and discomfort.\n\nReproduction: Bearded fireworms reproduce sexually, with separate male and female individuals. They release their gametes into the water, where fertilization occurs. After fertilization, the eggs develop into planktonic larvae, which eventually settle on the seafloor and transform into juvenile fireworms.

Their cooperative hunting technique is similar to that of the moray eel, with the Snakes flushing out prey from narrow crevices and holes. \nTriton Bay, Kaimana Regency, West Papua Province, Indonesia, \n3°55'0.7321 S 134°6'7.7298 E
