Snake

Snakes are reptiles that have no legs, but their skeletons show that they have remnants of legs and therefore must have had them many, many thousands of years ago. Snakes have a special way of moving and are covered with scales, which are larger on their stomachs. This means they can brace themselves against the ground and quickly slither away.  They are also good swimmers, and some can even climb trees, although not the snakes found in Sweden.  Here we only have grass snakes and vipers. They eat small animals and fish, and they stick out their tongues to smell. Snakes are good at sensing vibrations in the ground and disappear quickly if they notice someone approaching.
