All About Amphibians
Amphibians are cold-blooded vertebrates (having a backbone) that don't have scales. The word 'amphibian' means two-lives. They spend part of their lives on land and part of their lives in the water. Amphibians begin their life in water. They have gills and tails. They develop lungs and legs as they grow for their life on land.
American Bullfrog
Bullfrogs live in shallow areas of freshwater ponds, lakes and marshes where there a lot of plants. They may travel on to land when it rains. They use their powerful legs to leap up to 6 feet.
Bullfrogs eat fish, turtles, bats, rats, and water birds. They hunt during the day and at night and jump at their prey with their mouths open. Bullfrogs are eaten by herons, turtles, water snakes, and raccoons.
Bullfrogs have rough skin and are covered with tiny bumps. Male bullfrogs are smaller in size than females and have yellow throats.
Female bullfrogs can lay up to 25,000 eggs. Tadpoles are large and yellow-green in colour with dark spots. It can take up to 2 years before the tadpoles become frogs.
