Cave Diving for SCIENCE in Mexico!

Jonathan and Todd join cave biologists Fernando Calderon Gutierrez and Jairo Arroyave in a search for new forms of life in Aerolito Cenote on the island of Cozumel, just off the coast of the Yucatan peninsula in Mexico. AS ALWAYS please remember we are certified cave divers and these adventure episodes are not instructional. They are adventures! We do not show every step of the process for a very good reason...these videos are NOT INSTRUCTIONAL. Do not enter a cave (wet or dry) without proper training and equipment. Cave diving is exceptionally dangerous. If you want to do it, get certified for it. JONATHAN BIRD'S BLUE WORLD is an Emmy Award-winning underwater science/adventure series featuring underwater cinematographer/naturalist Jonathan Bird. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ ● Subscribe to Blue World https://www.youtube.com/c/BlueWorldTV/?sub_confirmation=1 ● Make a donation! https://www.zeffy.com/en-US/donation-form/blue-world ● Become a Member https://www.youtube.com/channel/UCFH-Qa1s6rQRTrQjFg8N84Q/join ● Check out our Extras Channel https://www.youtube.com/channel/UCXRF_NqOUBJszlmqBJVBkYA ● Blue World Merch http://www.blueworldtv.com/shop ● Support us on Patreon http://patreon.com/BlueWorldTV ● Instagram https://www.instagram.com/blueworldtv/ ● Facebook https://www.facebook.com/BlueWorldTV ● Twitter https://twitter.com/BlueWorld_TV ● Website http://www.blueworldTV.com ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ #scubadiving #cavediving #rebreather Chapters: 0:00 Tease/Open 1:05 Arrive in Cozumel 4:14 The Dive Begins 10:55 Down Into the Basement 15:16 Time to head back 19:03 Summary and Credits
