Another aquatic snake from southeastern Asia, this is quite a unique species, the last surviving member of its genus. Its most notable feature are the strange fleshy tentacles on its snout. These tentacles are actually highly sensitive mechanosensors, which allow the snake to detect movement in the water and strike at any unfortunate fish that swims nearby. Another interesting trait is the tentacled snake's incredible attack speed; it takes only 15 milliseconds for the snake to capture its prey.
