The Sea of Cortez is incredibly diverse with a vast array of blennies, jawfish, rays, massive schools of fish, seahorses, frogfish, Mexican Horn Sharks, and the list goes on and on. They have a large population of sea lions and a lot of whale activity on this particular trip, consistently seeing Pilot, Fin, and Sperm Whales. The Rocio del Mar is a family-owned liveaboard and a longtime partner of REEF.

We're wrapping up a busy and rewarding summer season for the REEF Ocean Explorers Education Program! We hosted virtual, in person, and field-based programs for ocean lovers of all ages, from inter-generational programs designed for grandparents and their grandchildren to learn about marine life of the Florida Keys together, to weeklong trips with classroom lessons, snorkeling and kayaking, and even online programs to help people experience the ocean from their home or classroom.

REEF Fest is an annual event for ocean lovers. It includes free educational presentations, diving, snorkeling, kayaking, nature tours, and socials. It's all happening on October 19-22 in Key Largo, Florida. You can check out all the details at www.REEF.org/REEFfest. We're excited to welcome an amazing lineup of guest speakers this year, including:

REEF Field Survey Trips are eco-vacations led by marine life experts. Each trip features daily dives and fish ID classes for both beginners and experienced surveyors. Divers, snorkelers, and families are all welcome. Only a few spaces remain on our Field Survey Trip to the Southern Sea of Cortez, happening this fall from Sept. 29-Oct. 6. Warm waters and calm seas make this a great time of year to dive in the Sea of Cortez. This unique body of water is separated from the Pacific Ocean by Mexico's Baja Peninsula.
