Taxidermy is the art of preserving an animal's body by mounting (over an armature) or stuffing, for the purpose of display or study. Animals are often, but not always, portrayed in a lifelike state. Animals are often, but not always, portrayed in a lifelike state.
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.

A Virginia opossum (Didelphis virginiana) playing dead A barred grass snake (Natrix helvetica) playing dead. Apparent death [a] is a behavior in which animals take on the appearance of being dead. It is an immobile state most often triggered by a predatory attack and can be found in a wide range of animals from insects and crustaceans to ...
A fresh pig carcass. At this stage the remains are usually intact and free of insects. The corpse progresses through algor mortis (a reduction in body temperature until ambient temperature is reached), rigor mortis (the temporary stiffening of the limbs due to chemical changes in the muscles), and livor mortis (pooling of the blood on the side of the body that is closest to the ground).
This course is designed for students who wish to pursue an interest in the life sciences. The College Board recommends successful completion of high school biology and high school chemistry [2] before commencing AP Biology, although the actual prerequisites vary from school to school and from state to state.
A well-researched form of deception is feigning death, familiarly known as "playing dead" or "playing possum", although specialists use the terms "tonic immobility" or "thanatosis". A wide range of animals, e.g. lizards, birds, rodents, and sharks, behave as if dead as an anti-predator adaptation, as predators usually take only live prey. [14]
Examples commonly found on land include blow flies, flesh flies, muscid flies, ensign flies and thread-horns. Other necrophagous flies are semi-aquatic, for example black flies and lake flies. [2] [14] Types of carrion fed upon include wildlife, [15] [16] [17] livestock and poultry carcasses, slaughterhouse and fishing discards, and human ...
Mice are the most commonly used mammal species for live animal research. Such research is sometimes described as vivisection. Vivisection (from Latin vivus 'alive' and sectio 'cutting') is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure.
