NPS Photo/J. Bonney ![]() YELL/Douglass Grand Teton National Park is home to an incredible variety of wildlife including several species of reptiles. Reptiles have dry, scaly skin and either lay eggs or bear live young. Reptiles are cold-blooded. They cannot maintain a constant body temperature like mammals. Instead they regulate their body temperature by moving into or out of sunlight. The park's cold climate limits the number of reptile species found here. ![]() Explore WildlifeFrom the tiniest shrew to the largest grizzly bear, wildlife draws visitors from around the world. ![]() NatureLearn about nature in Grand Teton. ![]() Bear and Wildlife SafetyLearn how to stay safe in bear country. ![]() Park Species ListsFind species lists for mammals, birds, amphibians, fish, reptiles, and plants ![]() Science and ResearchLearn about research in Grand Teton. |
