When the tadpoles come out of the eggs they wriggle around and fall into the water beneth them. The Poison Arrow Dart frog got its name from the Indians in the South American jungles. The Indians would make long wooded blowguns with darts in them for hunting. Then they killed the frogs to get their poison. They would then put the poison on the end of their arrow to go hunting.
Some frogs are cannibals.
That means they eat other frogs. Snakes eat frogs too. Bullfrogs eat mice and other small frogs. Bullfrogs may lay about 50,000 eggs. Frogs hibernate in the winter when it is too cold.
