Arowana

The Arowana grows to about 72 cm in length and can have a silvery or golden body. It's characterized by its elongated, crescent-shaped body and pronounced scales. Its lower jaw is more prominent than its upper jaw, giving it a very powerful bite. Its tongue is hard as bone, which is why it's nicknamed the Bony Tongue Fish, and fisherman know to handle it with care or risk getting bitten. It lives in freshwater with warm water temperatures.
