Taxidermy is practiced primarily on vertebrates [3] (mammals, birds, fish, reptiles, and less commonly on amphibians) but can also be done to larger insects and arachnids [4] under some circumstances. Taxidermy takes on a number of forms and purposes including hunting trophies and natural history museum displays. Unlike meat harvesting ...

In the case of sharks, the testes on the right side is usually larger [citation needed].The primitive jawless fish have only a single testis, located in the midline of the body, although even this forms from the fusion of paired structures in the embryo.

The conservation of taxidermy is the ongoing maintenance and preservation of zoological specimens that have been mounted or stuffed for display and study. Taxidermy specimens contain a variety of organic materials, such as fur, bone, feathers, skin, and wood, as well as inorganic materials, such as burlap, glass, and foam.
As documented in Frederick H. Hitchcock's 19th-century manual entitled Practical Taxidermy, the earliest known taxidermists were the ancient Egyptians and despite the fact that they never removed skins from animals as a whole, it was the Egyptians who developed one of the world's earliest forms of animal preservation through the use of injections, spices, oils, and other embalming tools.
