Photos by Pete McBride pedromcbride | Gliding Among Gentle Giants: The giant manta rays in the Revillagigedo archipelago, a biosphere reserve known as the “Galapagos of Mexico,” have the largest brain-to-size ratio of any cold-blooded fish and are some of the most magnificent creatures I’ve had the pleasure to swim with. Located some 540 kilometers (330 mi) south of Baja California, the waters surrounding the four volcanic islands of the archipelago contain some of the largest aggregations of sharks and manta rays in the world, as well as tuna, humpback whales, and five species of sea turtles. Since 1994, six nautical miles around the islands have been protected, creating a natural, vibrant habitat that is a rare model in today’s troubled oceans.
