David Andres: Sea of Cortez

David Andres: Sea of Cortez hero AZILL

The Sea of Cortez — nestled between the Baja California Peninsula and mainland Mexico — is a glittering extension of the Pacific Ocean, a living jewel with more than 2,500 miles of coastline. Made legendary in the 1940s by the great explorer Jacques Cousteau, who was awestruck by its staggering biodiversity, he famously named it “The Aquarium of the World.” The name has endured, and rightly so: this sea harbors over 900 species of fish, 695 species of vascular plants, 39% of all known marine mammals, and one-third of the planet’s cetaceans. It stands as the most biologically rich body of water on Earth — a cathedral of life beneath the waves. In recognition of its unparalleled ecological value, UNESCO declared it a World Heritage Site in 2005.

Yet even paradise trembles under threat. Pollution, coastal development, and relentless overfishing are eroding this fragile marine sanctuary. Mangrove forests — vital nurseries of life — are being cleared, while climate change fuels rising seas that swallow salt marshes and shift delicate coastal ecosystems. Recent fishing reports tell a bittersweet story: stormy weather has slowed the catch, yet the ocean still yields tuna, dorado, and marlin to those who brave its waters. The balance, however, grows ever more precarious.

For David Andres, the Sea of Cortez is more than a subject of study — it is a lifelong passion, a calling. His journey began with a dive beneath its surface, where he was captivated by its kaleidoscope of color and motion. Determined to share its beauty, he mastered underwater photography, bought a boat with friends, and made the sea his home. Over decades, he has watched its wonders and its wounds, translating both into art that calls the world to attention — a plea to save this heavenly sea before its song fades forever
