A frog is an amphibious animal. They belong to the order Anura.
Frogs can live on land and in fresh water. Frogs cannot survive in salt water. They hatch as tadpoles from eggs, which are laid by a female frog. The eggs are called frogspawn. Tadpoles have tails and gills. When they grow up, they lose their tails and gills and grow four long legs. Grown frogs can jump far with their legs. They have long tongues that they use to catch bugs. They make a sound called a croak. They sometimes live in tree, and some types of frog are capable of making poison. Frogs live all over the world. Different types of frogs are native to different countries and have different characteristics that relate to the environment of this country. If an overseas species of frogs is introduced to another country, the ecosystem can be hugely affected.
Frog legs are occasionally eaten as food in France, China, and the Midwest of the United States. The killing of frogs has an effect on the ecosystem. For example, frogs eat mosquitoes. If frogs are killed, then there are less frogs to eat mosquitoes, so more and more mosquitoes are born. Therefore, in these areas, there are more diseases that mosquitoes carry, because there are more mosquitoes.
