Ontogeny of Diving and Feeding Behavior in Juvenile Seaturtles: Leatherback Seaturtles (Dermochelys coriacea L) and Green Seaturtles (Chelonia mydas L) in the Florida Current

We compared activity, diving behavior and response to prey by Dermochelys coriacea and Chelonia mydas during their first 8–10 weeks of development. We reared juveniles in the laboratory and, at two-week intervals, released them in the ocean for a brief trial. Each turtle towed a device used to measure its dive profile. All turtles swam throughout their trials, but D. coriacea swam more slowly than C. mydas. Dermochelys coriacea dives had V-shaped profiles and older turtles made longer and deeper (up to 18 m) dives than younger turtles. Chelonia mydas dives were usually shallow (
