Snakes are not slimy, they are cool and dry. Some amphibians, like frogs, are slimy because they need to keep their skin moist, however, this is not the case with snakes. Snakes do not see people as prey and they only strike people in self-defense. Their tongues do not sting, lick or transmit poison. The tongue is a super-sensitive organ that permits the snake to make sense of its surroundings by combining both scent and taste cues.
Snakes shed their skin as a regular part of growing.
Like all reptiles, snakes grow throughout their lives. A snake's skin is similar to fingernail clippings.
