Marine Ecology

The Sea of Cortes is considered one of the richest in flora and fauna. This aquatic arm had its origin millions of years ago, with the tectonic Pacific and North American plate movements, which, during their collisions and frictions, created the continents and Baja California peninsula. The extraordinary wealth of this ecosystem is due mainly to the sunshine, the heat, winds and marine currents, which are ingredients that in this sea -baptized by Jacques Cousteau as the biggest aquarium of the world- unite in perfect combination for sea life. Millions of species inhabit the coast that surround La Paz, from colorful invertebrates such as Sea Urchins, Anemones and Corals to Whale Sharks, gigantic Manta Rays and several species of marine mammals, not to mention peculiar fish such as Cortes Angels and Seahorses. Many of these can be observed with just a mask and snorkel.

In addition, Baja California Sur is the birthplace for Gray Whales (Eschrichtius robustus). Each year from January until March it is possible to see mating, birthing and breeding, mainly around Laguna Ojo de Liebre in Guerrero Negro, Laguna San Ignacio and canals within Bahía Magdalena (Puerto San Carlos y Puerto Adolfo López Mateos), which is the closest body of water to La Paz and part of the county of Comondú, accessible by a three-hour drive on the transpeninsular road north.

In the city of La Paz you can find information about marine mammals, everything from the history of these animals to impressive displays of complete Gray Whale skeletons.
