The essential nature of creeping is the desire to avoid being seen, whereas crawling can merely indicate very slow movement. So a cat will creep up on its prey, while a spider can crawl slowly up a wall. Snakes don't crawl since they have no external limbs with which to crawl.
Keeping this in consideration, why does the snake slither?
Snakes can slither across flat surfaces without legs, but not entirely without help. That's because snake scales act as friction hooks which catch in rough points on surfaces, a new study shows. Strangely, the finding could eventually lead to robotic snakes that move more naturally.
What do you call the movement of a snail?
Most snails move by gliding along on their muscular foot, which is lubricated with mucus. This motion is powered by succeeding waves of muscular contraction which move down the undersurface of the foot. This muscular action is clearly visible when a snail is crawling on the glass of a window or aquarium.
Can you outrun a snake?
Snakes can't move between points nearly as fast as is commonly believed. Humans can easily outrun a snake but even better, we'll never have to! However, their striking speed should not be underestimated. Snakes are not aggressive in the true sense of the word.
