Socorro Giant Manta Expedition

June 23-July 3, 2021

SOCORRO - You can see mantas in many places around the world. But nowhere else boasts a population of giant mantas that literally seek out interaction with divers and snorkellers. The behaviour these giant mantas exhibit is almost inexplicable. These gentle giants with a wingspan up to 20 feet consistently approach divers for intimate eye-to-eye encounters. If you are able to be calm and still in the water, you are almost sure to experience what we call “manta love.” While mantas are the reason to voyage out to Socorro, there are lots of other animals to see, including schooling hammerheads and silky sharks, plus 8 other species of sharks, bottlenose dolphins that consistently hang out with divers at certain dive sites, large schools of pelagic fish, and, in season, humpback whales.


Here is a fun video from our 2016 excursion made by Alex Piper

THE PROJECT:  Students will be developing and collecting data via underbelly photographs and measurements for a new cutting edge cloud based database of giant mantas that we are developing using facial recognition software to allow researchers to learn more about these unknown pelagic animals. Blue Endeavors members may participate in this project or simply enjoy seeing the results in the evenings.

WHO IS ELIGIBLE: Current Blue Endeavors members and students who have completed a previous Blue Endeavors expedition. Additional training in Monterey may be required based on experience level.

PREREQUISITE CERTIFICATIONS: Divers must be certified in both Nitrox and Deep Diving, and comfortable shooting an SMB. Divers will have an opportunity to take these specialties and practice skills in Monterey before the expedition.

FINANCIAL AID: A friend to Blue Endeavors, Mike Lever, has donated some funds for students that have a financial need.  Please email vince at if you would like to participate, have a financial need or would like to help additional students participate on the trip.

STAFF & CHAPERONES: Similar to previous trips, in addition to the dive staff on the Nautilus, we will have Blue Endeavors instructors leading the dive operations, and a student chaperone, Bruce Hamren from The Athenian School.
