Amphibian is derived from the Ancient Greek term “amphibious” which means both kinds of life. It refers to animals that live both in the water and on land. Amphibians were the first vertebrates to leave the water and begin a new era of life on land. Amphibians began evolving during the age of dinosaurs, but diversified during the late Paleozoic or Carboniferous Period (354-290 million years ago).
Zion National Park is home to 6 species of frogs and toads, and one salamander. All of Zion’s anurans hibernate for the winter months and all of them must return to water in order to breed. In the springtime, warmer temperatures, rain and snowmelt create the right conditions for frogs and toads to begin emerging. Zion’s amphibian habitats include: grasslands, sandy shrub lands, marshes, meadows, pools, ponds, streams, rivers, and forest.
