These seas are abundant with marine life. Sea turtles, hammerhead sharks, giant manta rays with wingspan up to 12 feet, playful sea lions, and over 900 reef fish species. It makes sense why Jacques Cousteau dubbed it “the world’s richest sea.”

A Subterranean Spectacle

Due to the tremendous tidal flow and water movement that produce a distinct ecosystem, the undersea environment of the Sea of Cortez is unlike any other.

Every dive is a spectacle, thanks to the variety of marine animals drawn to this dynamic environment.

Divers can see the wonder of the marine environment up close thanks to the vast clusters of sea lions, dolphins, humpback whales, sharks, and other marine animals that flourish in these nutrient-rich waters.

Cabo San Lucas is The World’s Aquarium

Cabo San Lucas is a hub for migratory aquatic species at the meeting point of two seas. A distinctive and healthy ecosystem is created at the Sea of Cortez and Pacific Ocean confluence.

These waters are a migratory route for large groups of hammerhead sharks, silky sharks, mobula rays, and whales.

Divers may also encounter gorgeous mahi-mahi, graceful sea turtles, dazzling sardine tornadoes, and white-tip sharks.

Even marlin and orcas occasionally make an appearance. During the winter, if you’re fortunate, humpback whales may pass by, and you’ll be able to hear their beautiful sounds.

Some of the various animals found in Cabo San Lucas are mobula rays, which can be seen when scuba diving.
