Snakes are limbless and have elongated bodies covered in scales. And like all squamates, snakes are ectothermic.
They have flexible jaws which enables them to eat prey much larger than their head.Their bodies changes before and after a feed. A hungry snake has a smaller stomach volume, lower acidity and a regular heart volume. A full snake has extended intestines, increased stomach acid and almost double the mass of the ventricle of the heart to aid the digestion process.
185 species of snake are listed as threatened. Conservation efforts are concentrated on increasing awareness of the important role that snakes play in the ecosystem.
Snakes don’t have eyelids! They have a protective scale which covers their eye that is replaced every time they shed their skin.
