The Mexican government and the Pronatura Noroeste organization signed an accord to improve protection of San Ignacio Lagoon which serves as a refuge for gray whales.

Mexican President Felipe Calderon says he is cancelling the construction of a 30,000 room tourist resort in Baja California over concerns it could damage the nearby Cabo Pulmo coral reef and marine park

A centuries-old religious ceremony of an indigenous people in southern Mexico has led to small evolutionary changes in a local species of fish, according to researchers from Texas A&M University.

The skeleton, which is probably at least 10,000 years old, has disappeared from a cenote, or underground water reservoir, in Mexico's Yucatán Peninsula.

Cozumel combines the great reefs that one might find at the best dive spots around the warm Mexican Gulf waters with the laid back island life, where everything is close enough..

My first shark appeared head-on in the distance slowly swaying from side to side. With elegant grace and composure it continued towards the cage with mouth opened just enough to boast a healthy set of triangular teeth. Like the star of a grand performance, the shark held everyone in awe as it turned slightly just in front of the cage to examine an offering of tuna. It was a huge 14-foot (4m), 2175 pound (987kg) female. Her body was sleek and muscular, capable of high speeds if necessary. She ignored the bait and gave the caged divers a once over then slowly swam away, never changing her pace. Author, Peter Benchley, sure pegged it correctly when he referred to these creatures as “natural perfection”.

Located 386km (250 miles) southwest of the tip of Baja California and over 720km (446 miles) west of Manzanillo, the Revillagigedos are one of three Mexican island groups in the Pacific Ocean. All four islands that make up the Revillagigedos Archipelago are remote, volcanic in origin and offer some of the most unpredictable, wild diving in the world.

Yes, I know, Cozumel must have already been reviewed several times since you took up scuba diving, but the fact remains, that it is still one of the Caribbean’s top destinations for diving enthusiasts from all over the world—from the novice to the very knowledgeable — and now it’s safe again to go there, as Mexico has been cleared off the CDC’s travel warning list for swine flu. It’s time once again to enjoy the treats of this enchanting tropical paradise.

How to get out of the protective cage and swim with the Great White shark—that’s what Big Animals expeditions founder and leader, Amos Nachoum, helps the adventurous and steely-nerved diver and underwater photographer do.
