Ah, but you did eventually mention it. 

Laminforms are endotherms for the same reason that leatherbacks are
endotherms. They're big, bulky and swim alot. They are functionally

In my original reply, I meant to use ectotherm in place of cold-blooded. All
my examples were of functionally endothermic animals (insects, varanids, them
lamniform fishies). I was just trying to show that you can be active and still
be "cold-blooded."
