The two organisms do not have legs .They use muscles to move , but eventually what differs is the way they move .
The earthworm will use the advantage of soft and muddy surfaces to move while the snake uses the scales to grip to the ground .
On tight surfaces , the snake will use muscles to brace the back portion of its body while pushing to extend the front surface.
The snake then pulls its back part while dropping the front parts of their body .
This one helps to straighten and push to pull the back part of the body .
There are numerous method in which the organisms move apart from Concertina method and Serpentine method.
The answer is because of 'MUSCLES'
Snakes and earthworms do not have any legs . Which is why their walking style is different because they use muscles to move.
Each segment has a number very small bristles that earthworms use to help them grip the soil as they move. An earthworm creeps by using two different sets of muscles. Circular muscles loop around each segment, and longitudinal muscles run along the length of the body.
On the other hand snake uses the scales to grip to the ground .Snakes will push off of any bump or other surface, rocks, trees, etc., to get going.
