fleshing
n.— «Once the measurements are called in, the skin is carefully removed from the body in a process called “fleshing.” Excess fur is shaved off and a thin layer of hide is carved off the meat and membrane.» —“Taxidermists have skins on the wall” by Jonathan Tjarks WFAA-TV (Dallas-Fort Worth, Texas) Aug. 18, 2006.
