#BringTheStlZooToYou – August 4

Collard Lizards

At the Saint Louis Zoo’s Charles H. Hoessle Herpetarium most eggs are artificially incubated. This means that after the female makes her nest and lays her eggs in the animal habitat, the animal care team carefully moves the eggs into an incubator. We do this for several reasons. First, so that we can have control over the incubation temperature and humidity, which can be challenging in some of the larger habitats. Second, is  to keep the eggs safe. The last reason is to learn more about our animals’ fertility and development. If we have the eggs in an incubator we can easily monitor their development. Here you can see an animal care  team member candling some collared lizard eggs to check on their development. 

Update: There are now seven hatchlings! You can see little colored dots on each animal, this helps with individual identification so the care team can track the lizards’ health over time and make sure they are all thriving.

Calf Update:

We really wish we had good news to share about the health of the elephant calf, but we do not. Although at times the calf has shown signs of being stable, he has had multiple setbacks related to his underdeveloped feeding response as well as his ability to digest and stay hydrated. The calf continues to receive intensive care from the Elephant Care Team of keepers and veterinarians. This picture is from July 30, 2020, and shows members of the Elephant Care Team providing IV fluids during a veterinary evaluation. We appreciate your continued support and positive thoughts.


Welcome back Eileen Duggan! Thanks for visiting. We hope you enjoyed your walk around the Zoo! #MyStlZooVisit
