Reptile and Amphibian Discovery Center had 5 average-sized terrariums on the left hand side, and 3 average-sized and 6 small terrariums on the right hand side. The 5 terrariums on the left contained: eyelash vipers mixed with poison dart frogs (I only saw Dedrobates tinctorius azureus), a desert terrarium split in two levels, with a gila monster in the lower level and 2 chuckwallas and a desert iguana in the top level (there was also a label for Arizona mountain kingsnake, but I did not see it), northern copperhead mixed with eastern rat snake, a timber rattlesnake, and a dusky pygmy rattlesnake. The 3 larger terrariums on the right contained: a prehensile-tailed skink mixed with Solomon Islands leaf frogs; emerald tree boa and Corallus hortulanus mixed with 2 matamatas, and a cave-like terrarium for cave salamanders (Eurycea lucifuga), which was empty on the day of my visit. The 6 smaller tanks housed an axolotl, spotted turtles, tiger salamanders, Thailand black tarantula, a lesser siren (I believe it was the first for me, and very active), and a hellbender. At the end of the building, there are 2 larger exhibits: one for an African dwarf crocodile and another for green tree monitor mixed with White's tree frogs (I only saw the monitor)
