Golden Poison Dart Frog
Small and cute this frog may be, but it's also probably the most poisonous animal on Earth. This tiny frog is so full of poison that even touching it can be dangerous for humans. In fact, a single golden poison dart frog carries about 200 micrograms of toxins in its skin, enough to kill 20,000 mice or 10 humans.
This one is safely looked after in
London Zoo Regents Park.
