Frogs

The dart frog

Poison Dart Frog are Considered to be one of the most toxic animals on Earth, golden poison dart frogs have enough venom to kill ten grown humans. The Poison Dart Frog is not a very large amphibian as it typically weighs about 2 to 7 grams (0.07-0.25 oz) and is only 1.5 to 6 cm (0.6 to 2.4″) long. There are about 175 different species hanging out in the tropical jungles of Central and South America.  


The Poison Dart Frog greatly depends upon the large leaves of the Rain-forest to provide much needed shade from the hot Tropical sun.


Poison dartfrogs are small colorful frogs. They live in warm humid habitats. Poison dart frogs eat meadow plankton and small insects. Poison dart frogs got their names because some tribes in the rainforest took the poison off of the frog and put it on their arrows to make deadly weapons. Poison dart frogs can be almost any bright color. Some snakes have evolved immunity to these compounds and are thus able to prey upon adult frogs. A snaked called Leimadophis epinephelus has developed a resistance to their poison and will actually feed on the Poison Dart Frog.

Golden Poison Frogs breed during the rainy season and the female lays her eggs in moist leaf litter or under rocks. The male fertilizes the eggs then he regularly visits them until they hatch. Once the tadpoles have hatched the male carries them on his back to a larger area of water where they can complete their metamorphosis.
