Mammals, reptiles, fish, insects, and birds are all just as home off the beach in Costa Rica as they are within the country's borders. Warm Pacific and Caribbean currents mean that the amount of life encountered in the saltwater around the country is as diverse and in as great a number as on land. Scuba divers, fishermen, and anyone who happens to go out for a pleasure cruise will be able to attest to this truth.

Endangered wildlife in the ocean have also been granted areas of refuge where the government holds sway over territorial waters. This is especially important off of Cocos Island, where large schools of hammerhead and more solitary whale sharks are at risk.
