Snakes

Snakes have no external ear opennings..All snakes have a backbone (They are vertebrates) but lack limbs , eyelids and external ear openings. Snakes have a specialized row of scales along the underside of their bodies , the ventrals some families of snakes do retain vestigal pelvic gridles none of them have pectoral girdles snakes have unique skulls- the bones of their upper jaws are not united at the snout but are free to move away from one another , so allowing the passage of larger prey snakes are long , slender vertebrates without legs . This definition is not enough to separate snakes from some other groups of animals , through snakes are reptiles and branch of zoology that deals with this class of animals is known as 'Herpetology' derived from the Greek word herpeton , which means 'a creeping thing' .

In the early days of zoology all lowly animals such as amphibians and reptiles were lumped together in this group of 'creeping things' and the word 'herpetology' was coined to encompass all of them . The earliest known fossil creatures resembling snakes are from the lower Cretaceous period some 130 million years ago.
