Leopard Frogs were once widespread across the Navajo Nation, but now are the most endangered amphibian here. Their body color varies from green to brown, but they can be recognized by their dark circular spots and two light-colored lines on the sides of their back. They live in habitats with permanent water, such as ponds, swamps, marshes and slow moving streams. Like all frogs and toads, they lay eggs in the water and have aquatic larva called tadpoles.

Frogs and Toads are called "Ch'ąl" in the Navajo language. Traditional Navajo People consider them as sacred and have great respect for frogs and toads. It is said that they are the controllers of moisture on earth. One should not kill or harm frog and toads.
