Skinning

Skinning is the act of skin removal. The process is usually done with animals, mainly as a means to prepare the muscle tissues beneath for consumption or for use of the fur or tanning of the skin. The skin may also be used as a trophy, sold on the fur market, or used as proof of kill wha bounty (reward) from a government health, agricultural, or game agency, in the case of a declared pest.

Two common methods of skinning are open skinning and case skinning. Typically large animals are open skinned and smaller animals are case skinned.

Skinning, when it is performed on live humans as a form of capital punishment or murder is referred to as flaying.
