Driftfish, belonging to the Nomeidae family, are a group of marine fish found in tropical and subtropical waters worldwide. They are known for their unique behavior of drifting along with ocean currents, often associating with floating debris or seaweed. Driftfish species vary in size, with some reaching up to 50 cm in length. They have elongated, compressed bodies, and their dorsal and anal fins are continuous with the caudal fin. Driftfish are opportunistic feeders, preying on small fish, crustaceans, and plankton. They are also known to be bioluminescent, emitting light to attract prey or communicate with other driftfish.
