Featherback fishes, which belong to the family Notopteridae, are air-breathing, freshwater fishes. They inhabit quiet waters across a geographic range that includes Africa, Southeast Asia, and India. These nocturnal, predacious fishes are characterized by their long bodies and specialized anal fins that allow them to swim both forward and backward.123
