Crocodiles and alligators are amongst the fiercest hunters ever to have lived on our planet. Another reptile that resembles them in body and behaviour is the gharial, found only in the Indian subcontinent. The earliest ancestors of these reptiles lived around 250 million years ago, when dinosaurs waked the earth. Their body has not changed much in all these years. For this reason, they are sometimes called "living fossils".
A snake never stop growing. It continues to grow longer and thicker, even when it is old. The heaviest snake in the world is the Burmese python. It weighs around 200 kilograms, which is almost the weigh of a Siberian tiger. Another giant mover is the Reticulated python-the longest-known snake in the world. One Reticulated python from Indonesia is over 32 feet in length!
