Monkeys, parrots, jaguars, tapirs, and toucans inhabit the primitive rain forest of Costa Rica which lines the Golfo Dulce, or Sweet Gulf. Nature preserves and isolated beaches provide sanctuary for a great diversity of wildlife. The Golfo Dulce is home to the highest concentration of biodiversity in Costa Rica. The tropical haven includes species and habitats such as sea turtles, dolphins, humpback whales, mangrove forests and estuaries.
