They actually shed they're skin as a whole
We do ! It's just that we shed our skin in bits and pieces (that's where most of the household dust comes from - dead skin cells !) Reptiles on the whole, shed their skin in one piece.
We all shed our skins, monkies too, but not in one piece like snakes do. Rather it comes of in small flakes as new skin surfaces beneath it.
Humans are constantly shedding their skin; dead skin cells are one of the major components of the dust you get around the house. Because they r not adapted to these types of surroundings
All reptiles shed their skin. Reptile skin doesn't 'stretch' like ours does. Instead, when the current skin gets too tight, they grow another one underneath. They shed (or slough) the old skin, and the new skin allows them to grow a little more.
No crocodiles do not have a shell, but contail hard scaly skin that protects them from injury. Images of crocodiles and more information on the subject can be found here: http://en.wikipedia.org/wiki/Crocodile
Snakes shed because there skin does not grow with there body, as human skin grows with the body. Snakes shed more when there young and shed less when there older. Rattlesnakes grow a new layer of there rattle every time they shed, so the older the louder.
Humans do shed skin. When skin cells die, it falls off your body it's called Desquamation. Every hour nearly 40,000 skin cells are shed, and it takes one skin cell about a month to complete the desquamation process. In fact, person from 2009 that says humans don't shed, the dust in your home is mostly dead skin cells. Your dead skin literally falls off your body.
It grows a little bit. Reptile skins are not infinitely flexible thus as the animal grows it needs to shed its old skin and grow a new, large one.

Gaboon vipers shed their skin frequently and typically do so in one piece. They may shed every 4-6 weeks, with younger individuals shedding more frequently than older snakes. It's important to ensure proper humidity levels in their enclosure to support successful shedding.
yes it molts or shed and leaves it's scaly skin behind and grows a new one
