With a biodiversity greater than most countries in the world, Costa Rica hosts a plethora of animals. From invertebrate to mammal, birds to reptiles, amphibians to fish, there are representatives from nearly 5% of the species that live on planet Earth found in Costa Rica's border. And those animals that swim through the marine borders are not to be forgotten either.
The food chain shows itself off in grand array here. Hundreds of thousands of different insects provide a base for those higher up, and those higher up help to support some of the greatest carnivores in the Western Hemisphere. Of course, humans can really mess up the chain, so it is very important for continuing conservation efforts. There are several endangered species in Costa Rica.
