They are native to Asia and Africa, and some species have been introduced to other regions, Key Characteristics Body Shape: Snakeheads have a long, slender, and cylindrical body, with a small head and a large, protractile mouth. Fins: They possess long, continuous dorsal and anal fins that extend nearly to their tail fin. Scales: Some species have large scales on their head. Eyes: Their eyes are located on the top of their heads. Breathing: They have a suprabranchial organ (primitive lung) that allows them to breathe air, enabling them to survive in low-oxygen environments and even out of water for a short time.
