Coldly goes the sloth

James' question in class about sloth body temperature made me curious, so I ran a quick search and came up with a couple of links for your enjoyment. Indeed, sloth body temperature is lower than most mammals. Whether they're slow because their body temperature is low or their body temp is low because they're slow is another question. And I have no idea how this effects the relative activity rate of slothian enzymes....though I am sure you all can make some hypotheses about the optimal temperature of them...maybe even something about the range of temperatures they function over.
