    Orange-spotted snakehead

    Channa aurantimaculata

    The snakehead family includes about 50 species. They are found in Asia and Africa. The orange-spotted snakehead is found only in a small region of India, in eastern Assam. There it is common only in the Brahmaputra River and its tributaries.
    A so-called labyrinth organ in the gill chamber, which consists of a richly folded tissue with a good blood supply, enables snakeheads to breathe air. This enables them to survive on land for up to 4 days, as long as they are kept moist at the same time. They can also travel distances of up to 400 meters on land. To move around, they perform writhing movements with their bodies.
