Reptile House: A Cold-Blooded World December 4, 2010

A stroll around its perimeter allows you to safely view an amazing collection of pythons, cobras, boas, rattlesnakes, desert tortoises, and Gila monsters up close -- about 100 species in all! Because you're on the outside looking in, you're not bothered by the heat and humidity required to maintain some of our reptiles. Each reptile's enclosure is designed to look like the resident's natural home.
