Thousands of different marine organisms live here, including 236 species of fish, many of which are protected. Seasonally, whales and other great sea creatures arrive here, many of which are protected by Mexican and international legislation, such as the whale shark and marine turtles. Of the seven species of these marine reptiles that exist in the world, five arrive off this coastline, to nest on our beaches, or breed and forage in our seas.

Taking into consideration environmental and normative culture, commercial fishing is prohibited in the central and surrounding areas. The park provides a protected space for commercial and non-commercial marine species and in some cases is a regenerative area for hundreds of other species.

The mountains and waters surrounding the park are truly beautiful; the tranquil beaches combine perfectly with the desert areas inviting visitors to take in the landscape, submerge themselves into a vivid and colorful watery world, engage in sport fishing or go hiking in the natural terrain discovering the marvelously diverse desert flora and fauna. Cabo Pulmo National Park is an exciting, true paradise of color and form, where natural beauty overflows and where environmental and scientific knowledge are enhanced through the study and research of its ecosystem and the complex relationships between the humans, animals and plants that live there.

Unfortunately, this coral reef system faces a number of threats: coral de-colorization; unregulated fishing and snorkeling/scuba-diving; and worst of all, the increasing sediment discharges that would result from the changes in soil composition through high impact tourist developments. Yet another threat is rising unrestricted vehicular traffic along the beaches, which threatens the survival of the nests of two species of sea turtle that lay their eggs in the sands on the coast (the Olive Ridley and the Leatherback).
