About Cayman Marine Lab..

Established in 1986, Cayman Marine Lab caters to families and individuals interested in a smaller eco-diving experience. Cayman Marine Lab will run with as few as 2 or a max of 10 divers, we like small groups. The atmosphere is very informal and Cayman Marine Lab is the only marine eco-tourism operation in the entire Caribbean run by a "real" marine biologist, Tom Byrnes Ph.D.

Trip Advisor Testimonials

My husband and I had a great week of diving, May 13-20, 2014, with Tom Byrnes. We went to dive sites on the North Wall and South. Rather than diving named sites, we anchored in sandy spots and went to areas rarely seen by most divers, with pristine corals and sea life.


I just spent another week diving Tom Byrnes and CMD. It was truly another awesome experience as it always is. Diving with CML defines adventure diving. Typically they anchor in a sandy location adjacent the wall. These are areas not used by other dive operations.
