Brown Spider Monkey

Is a critically endangered species of spider monkey, a type of New World monkey, from northern Colombia and north-western Venezuela.
The Brown Spider Monkey is now a highly threatened species, and some populations have already been extirpated. There is ongoing habitat loss within its range, and it has been estimated that 98% of its habitat already is gone. It is also threatened by hunting (in some regions it is the favorite game) and the wild animals trade.

The brown spider monkey is among "The World's 25 Most Endangered Primates" (http://www.primate-sg.org/PC24.htm)
