Bears are active in Grand Teton
Black and grizzly bears are roaming throughout the park--near roads, trails and in backcountry areas. Hikers and backcountry users are advised to travel in groups of three or more, make noise and carry bear spray. Visitors must stay 100 yards from bears. More »
Amphibians are some of the most unusual and important species found in the park. The word amphibian comes from the Greek words meaning "double life", and refers to their unusual two-stage life cycle. An amphibian begins life as an egg, laid either in water, or in some other wet environment. The larvae hatch and spend their time in water breathing through gills. They then undergo a metamorphosis into an adult form that breathes using lungs. While adults are considered terrestrial, amphibians continue to spend most of their lives near water. Unlike reptiles that have dry scaly skin, amphibians have moist, smooth, glandular skin with no scales, and they have no claws on their toes.
