ZooPax are demonstrations of specific animal adaptations that can be seen in animals at the Fort Worth Zoo. The point of ZooPax is to encourage students to look closely at some specific animal feature. Each ZooPax unit consists of a brief description of an animal feature and links to 10 or more animals that demonstrate variations in that feature. The ZooPax below were developed as a pilot project for WhoZoo. More ZooPax will be introduced if response to this first set is favorable. Please E-mail me at zoopax@whozoo.org with comments and suggestions.
