Convergent adapations between leatherbacks and cetaceans/pinnipeds. They all show the 'typical' dive response, for example, but to varying degrees. Leatherbacks' blood and muscle oxygen stores are much lower than those of marine mammals, but then again so are their metabolic rates, so they can still do the prolonged dives. Check out my other post about Gigantothermy and the paper cited there: Wallace and Jones (2008) JEMBE. We go over physiological adaptations for diving in leatherbacks there. And if you're at UNC-Wilmington, go look up Dr Amanda Southwood, if you haven't already. She's one of the premier sea turtle physiologists in the world -and a good buddy of mine!

The article seems to suggest so, but the citiations dont' address it specifically... Marine Herp wasn't an offering at UNC-W, so I honestly have no idea...
