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).
These processes release compounds such as cadaverine and putrescine, that are the chief source of the unmistakably putrid odor of decaying animal tissue. [2] Prime decomposers are bacteria or fungi, though larger scavengers also play an important role in decomposition if the body is accessible to insects, mites and other animals.
In water ecosystems, relatively little waste collects on the water bed, and so the progress of decomposition in water takes a more important role. Investigating the level of inorganic salts in sea ecosystems shows that unless there is an especially large supply, the quantity increases from winter to spring—but is normally extremely low in summer.
It can also be fatal to animals like dogs and horses if consumed. Large brown mats of decaying algae were present along the shores of coastal Manatee County and Anna Maria Island this week.
By Ivan Moreno ALBUQUERQUE, N.M. -- New Mexico authorities are making a stink after an odor wafting from a New Mexico property led them to a foul discovery -- dozens of dead animals, including the ...
The "smell of death" research has been permitted as evidence in court. In the 2011 Caylee Anthony case, in which Casey Anthony was accused of having murdered her 2-year-old daughter, the scent from inside the trunk of the car in which she was accused of having stored a dead body was collected and then assessed by an expert witness.

The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules , and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body ...
