Costa Rica supports an enormous variety of wildlife! In large part, the biodiversity is accredited to three main factors:
1) Its geographic position between the North and South American continents
2) Its neotropical climate
3) Its wide variety of habitats.
Costa Rica is home to more than 500,000 species, which represents nearly 4% of the total species estimated worldwide, making Costa Rica one of the 20 countries with the highest biodiversity in the world.
One of the principal reasons why Costa Rica's wildlife is so diverse is because the country, together with the land of Panama, formed a bridge connecting the North and South American continents approximately three to five million years ago. This land bridge allowed the very different flora and fauna of the two continents to mix.
