Great info...and kudos to you for patiently searching!

I know I'm probably being annoying, but I just have to split hairs on this one. Reptiles do not hibernate. It's a metabolic process reserved for mammals. Reptiles brumate. I know a lot of people use the terms interchangeably, but it's not scientifically accurate. If you think of the Colombian tegus, they slow down for the winter, probably because of the cooler weather, but they do not brumate like the Argentines.

Sorry, I'm not picking at you, Serpent's Coil. It's a really interesting post to hear about the origination and photography of the blue tegu. I guess the science teacher in me just couldn't leave the brumation/hibernation part left alone.
