Extinct animals are animals that used to live on earth but due to natural or man-made causes have all died out.The species is then called extinct.
That's true, but there is a little more to it. I will give a minimum amount: Most of the extinct animals were prehistoric. The reason why all the prehistoric animals are whiped out today is because of a meteor. One of the reasons why animals today are extinct is because of the loss of habitats, due to cutting down froests, and other living places.
