Frogs are a kind of small animals belonging to a group called vertebrates (animals with backbones) known as amphibian. This means that they live past life in water and other part of it on land. Amphibians are cold-blooded animals. This means that their body temperature is the same as the surrounding temperature. Their skin absorbs water into their body, so they do not have to drink water to survive. Frogs have strong hind leg to enable them leap forward at a great distance. The front legs or arm are short. They are used to prop the frog up when it sits.
Frogs are special. They can breathe by means of the lungs and also through their skin. this is because of the way their hearth is formed. It has 3 chambers instead of the normal 4. The frogs diet consist mainly of insect, small animals. Most frogs have a sticky tongue. To catch an insect, the frog flips out its tongue rapidly, gets the insect and refracts its tongue. Frog will shallow their prey in one piece because they only have teeth in the jaw. Doesn't do much chewing! Frogs hunt mostly at night.
Frog have enemies that will eat them. They are bats, herons, fish, raccoons, turtles, snakes and even human beings. Human beings eat them and also destroy their natural habitat and prevent them from extinction. Different species of frogs have different kinds of protection. some have poison glands in their skin. The skin will secret and cover the body with the poison and this will deter the enemy from eating them. Some use colors to protect themselves.
Frogs are friendly to human being. They are a source of food in some countries. they eat insect, some of which are serious pests. We use them for medical research to test new drug and student dissect them to learn about anatomy. They are also part of the ecosystem which means that whatever happens to them will affect other animals and even us in different ways.
