While sometimes the origin and form of pollution is visible and easy to determine, other times it can be a mystery as to what exactly is causing the death of animals. Through constant and consistent observation of habitat analysis, humans can help prevent the loss of animal life by recognizing the early signs of pollution before the problem ...
Researchers use variation on humpback whale flukes to identify and track the animals. Photo-identification is a technique used to identify and track individuals of a wild animal study population over time. It relies on capturing photographs of distinctive characteristics such as skin or pelage patterns or scars from the animal.
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.

The definition of "longest-living" used in this article considers only the observed or estimated length of an individual organism's natural lifespan – that is, the duration of time between its birth or conception, or the earliest emergence of its identity as an individual organism, and its death – and does not consider other conceivable ...
These animals can be domesticated or wild, and sometimes they find both types of remains at sites. [12] In addition to helping us understand the past, zooarchaeology can also help us to improve the present and the future. [13] Studying how people dealt with animals, and their effects can help avoid many potential ecological problems. [13]
Animals first appear in the fossil record in the late Cryogenian period and diversified in the subsequent Ediacaran period in what is known as the Avalon explosion. Earlier evidence of animals is still controversial; the sponge -like organism Otavia has been dated back to the Tonian period at the start of the Neoproterozoic , but its identity ...
