Sea Mammals of Costa Rica
More than twenty species of dolphin and whale may find their way through Costa Rican waters. Nearly ten species are reliably found at different times of year. Large marine mammals of the order Cetacea (whales and dolphins) are usually migratory. However, coasts of equatorial land pose an attractive destination or detour. Shallow reef areas, such as those on the Caribbean or Southern Pacific coasts of Costa Rica, provide valuable sighting areas for marine wildlife. Creatures living in the reef and visitors that come to feed present a fascinating sight.
