Blue was born at the Cayman Island Turtle Farm in 1996, then moved to the University of British Columbia. Here he and his brother Mini participated in a study helping biologists learn more about green sea turtle physiology. When they became too big for their enclosures, they were donated to Marine Life.
Blue’s coloration looks very similar to Donatello, but he is larger in size. He also has squinted eyes, whereas Donatello’s are large and round. Blue is very calm, and is a fast learner in underwater training sessions with Marine Life scuba divers.
