Question

how can snakes move wothout legs?

Answer 1

Snakes have special enlarged belly scales or scutes; each scute occupies the entire ventral width and is associated with special muscles that can move independently. These muscles extend between the scutes and also link the scutes with the ribs

See photograph of the scutes:

and diagrams of the muscles:

Especially heavy snakes (such as boas) can move in a straight line, slowly but powerfully, by means of these scales. Others use also body undulations in which the body is anchored by these scutes against the substrate (be it firm soil, the bark of a tree or sand). In all cases, mobility is enhanced by the large amount of vertebrae (with special joints) and ribs.

Answer 2

It has to do with their body structure. They use their muscles and scales to move in different ways depending on desired speed and terrain. Below is the first link that came up on google.com
