Venezuela pebble toads have a very unusual defence mechanism, shared with only a few close relatives. They roll themselves up into a ball and bounce down the hill, away from danger. These tiny amphibians weigh so little that if they hold their muscles rigid, the bouncing doesn't damage them at all. Pebble toads also breed communally, so a single nest can contain over 100 toads. One nest found had 103 toads and 321 eggs in it.
Scientific name: Oreophrynella nigra
Tiny pebble toads have a unique defensive strategy against tarantulas.
In super slow motion, the amazing pebble toad tumbles down a cliff face to escape a toad-eating tarantula. It is so small and weighs so little that it doesn't even hurt itself as it bounces off the rocks. Now that's rock'n'roll!
