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
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.
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
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.
One pound
yes it molts or shed and leaves it's scaly skin behind and grows a new one
It doesn't grow as the snake gets bigger. The skin stretches up to a point and then splits and is shed. A new skin has already developed under the one about to be shed. Another thing is that snakes are not at all slimy to the touch
They shed their skin to grow. Unlike humans, who's skin is continuously renewed, reptile skin doesn't stretch as they grow. Therefore - periodically, then shed the old skin after forming a new one underneath.
