With stunning mountainous desert landscapes topside and fascinating rocky reefs and pinnacles underwater, the northern Sea of Cortez is a favorite destination for REEF surveyors. The unique marine life, including nudibranchs, rays, eels, octopuses, blennies, jawfish, and even sea lions, make it easy to understand why Jacques Costeau nicknamed this region, "the world's aquarium." In addition to numerous fish and invertebrate families, attendees may also see pilot and sperm whales while in transit and have the opportunity to snorkel with whale sharks. The plankton-rich currents of the Pacific along the coast of California and Mexico, along with the sheltered waters of the Sea of Cortez, also create a great opportunity to encounter manta and mobula rays. The Rocio del Mar is a family-owned liveaboard, and a longtime partner of REEF. The boat is a spacious 110-foot vessel with an excellent crew.
