Snakes


Snakes are reptiles (cold-blooded creatures). They belong to the same group as lizards (the scaled group, Squamata) but form a sub-group of their own (Serpentes).Snakes have two legs but a long time ago they had claws to help them slither along. Snakes are not slimy. They are covered in scales which are just bumps on the skin. Their skin is hard and glossy to reduce frinction as the snake slithers along the ground.

Snakes often sunbake on rocks in the warm weather. This is because snakes are cold-blooded and they need the sun’s warmth to heat their body up. Most snakes live in the country. Some types of snakes live in trees, some live in water, but most live on the ground in deserted rabbit burrows, in thick, long grass and in old logs. A snake’s diet usually consists of frogs, lizards, and mice and other snakes. The Anaconda can eat small crocodiles and even wild boars.

Many snakes protect themselves with their fangs. Boa Constrictors can give you a bear hug which is so powerful it can crush every single bone in your body. Some snakes are protected by scaring their enemies away like the Cobra. The Flying snakes glide away from danger. Their ribs spred apart and the skin stretches out. Its technique is just like the sugar glider’s.
