Ecuador occupies only 0.2% of the Earth's land surface, but it is home to 579 known amphibian species. In terms of amphibian biodiversity per square kilometer, Ecuador is among the highest in the world -- Ecuador actually has approximately 65 times more amphibian species per square kilometer compared to the USA! This incredible diversity is due to the large variety of ecological niches created by the Andes mountains, which cross the country from north to south, dividing the country into three distinct regions: the Amazon, the Coast and the Andes. At least 257 of Ecuador's amphibian species are found nowhere else on Earth. Ecuador's amphibians are incredible: glass frogs with translucent skin on their belly, allowing you to view their beating hearts; colorful frogs of all kind; and amazing behaviors like poison dart frogs carrying tadpoles on their back. With all this in such a small country, Ecuador is the perfect place to enjoy and learn about the unknown and enigmatic world of amphibians.
