N,N-Diethyl-meta-toluamide, also called diethyltoluamide or DEET (/ d iː t /, from DET, the initials of di- + ethyl + toluamide), [1] [2] is the oldest, one of the most effective, and most common active ingredients in commercial insect repellents.
A deer (pl.: deer) or true deer is a hoofed ruminant ungulate of the family Cervidae (informally the deer family).Cervidae is divided into subfamilies Cervinae (which includes, among others, muntjac, elk (wapiti), red deer, and fallow deer) and Capreolinae (which includes, among others reindeer (caribou), white-tailed deer, roe deer, and moose).
Most species do not have population estimates, though the roe deer has a population size of approximately 15 million, while several are considered endangered or critically endangered with populations as low as 200. One species, Père David's deer, is extinct in the wild, and one, Schomburgk's deer, went extinct in 1938.

More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.
