... they spend most of their life in the ocean and perform deep and/or long dives. In this study, we examined the relationship between heart rates and metabolic rates in captive loggerhead turtles, Caretta caretta , to estimate oxygen consumption rates during each dive based on heart rates. The oxygen...
