Costa Rica is as renowned for its marinelife as for its terrestrial and avian fauna—most famously, perhaps, for the billfish (marlin and sailfish) that cruise the deep blue waters offshore, and for tarpon and snook, feisty estuarine and wetland game fish. The former swim seasonally in the warm waters off the Golfo de Papagayo and Golfo Dulce; the latter are concentrated in the waters of the Río Colorado and Caño Negro.
Sharks are forever present in Costa Rican waters. They seem particularly to favor waters in which marine turtles swim. Isla Cocos is renowned for its schools of hammerhead sharks as well as giant whale sharks (the world’s largest fish), which can also be found hanging out with giant grouper, jewfish, and manta rays in the waters around the Islas Murciélagos, off the Santa Elena Peninsula of Guanacaste.
Whales—notably humpbacks—can be seen predictably along the west coast of Costa Rica December–October, when they migrate from both Antarctic and northern Pacific waters to mate and give birth in the warm waters off the Costa Ballena.
