A day for our oceans

To celebrate World Oceans Day, we're swimming through a shoal of jack fish just off the coast of the Mexican state of Baja California, in Cabo Pulmo National Park. The coral reef in this marine park in the Sea of Cortez is estimated to be about 20,000 years old. Jacks are clearly plentiful, but divers and snorkellers in Cabo Pulmo can also come across many other species of fish and marine mammals, including sharks, whales, dolphins, tortoises and manta rays.
