Baby Poison Dart Frog
These amphibians are often called "dart frogs" due to indigenous Amerindians' use of their toxic secretions to poison the tips of blowdarts.
Most species of poison dart frogs are small, sometimes less than 1.5 centimetres (0.59 in) in adult length, although a few are up to 6 centimetres (2.4 in) in length. They weigh about 2 grams.
Once the tadpole has hatched in a pool of water somewhere on the forest floor, one parent, usually the male, will retrieve the tadpole and attach it with mucous secretions to its back and carry it up a tree. There he will deposit his young into a water-filled bromeliad where it will develop into a new frog. This frog was found at a height of 36 metres (118 feet)!
