The Pebble toad  (Oreophrynella nigra) of Venezuela moves slowly, getting around by walking rather than hopping. They live in areas where there is a bit of small vegetation poking out of otherwise bare rock faces. They eat all kinds of different insects and are either dark brown or black in colour. What makes this species stand out the most though, is their incredible survival strategy. When facing a predator the Pebble toad will curl into a ball and roll away, tumbling over rocks to escape.
