The most eye-catching feature of the sawfish is its saw-like snout, called a rostrum. The rostrum is covered with motion- and electro-sensitive pores that allow the fish to detect movementand even the heartbeat of potential prey buried in the ocean floor. Once successful, the rostrum is then used as a digging tool to unearth buried prey.
