Signed for a handful of native reptiles and amphibians, but all I saw was a Southwestern Pond Turtle. Not sure how anyone would see a small lizard or newt in here.
@Coelacanth18 - I am fairly confident that the only current collection residents are the southwestern pond turtles. I have never seen any of the other signed animals, other than some obviously wild spiny lizards sitting on the edge of the exhibit walls. The Zoo is not listed as a holder for any of the other signed species in ZIMS, either.
This exhibit, which is a potentially fantastic one for small reptiles and amphibians, has regressed badly over the years. It seems as if every zoo nerd who visits, including me, spots a turtle or two and that's it. What a shame.
