An endangered species is a species of organisms facing a very high risk of extinction. The phrase is used vaguely in common parlance for any species fitting this description, but its use by conservation biologists typically refers to those designated Endangered in the IUCN Red List, where it is the second most severe conservation status for wild populations, following Critically Endangered. There are currently 3079 animals and 2655 plants classified as Endangered worldwide, compared with 1998 levels of 1102 and 1197, respectively. The amount, population trend, and conservation status of each species can be found in the Lists of organisms by population.
Many nations have laws offering protection to conservation reliant species: for example, forbidding hunting, restricting land development or creating preserves.
Brown spider monkey
The brown spider monkey or variegated spider monkey is a critically endangered species of spider monkey, a type of New World monkey, from northern Colombia and northwestern Venezuela. Its taxonomic history has been confusing, and in the past it has been treated as a subspecies of either the Geoffroy's spider monkey or the white-fronted spider monkey. Like all spider monkeys, it has very long, spindly limbs and a lengthy prehensile tail which can almost be called a fifth limb. The tail has a highly flexible, hairless tip with skin grooves which improves grip on tree branches and is adapted to its strictly arboreal lifestyle. The brown spider monkey has a whitish belly and patch on the forehead, and – highly unusual among spider monkeys – the eyes are sometimes blue. The brown spider monkey is now a highly threatened species, the population is estimated to have decreased by at least 80% and some populations have already been extirpated. Few remaining populations are of adequate size to be viable long-term. Almost 60 brown spider monkeys are present in various ISIS-registered zoos (mostly in Europe), but breeding success
