This is a list of large extant primate species that can be ordered by average weight or height range. There is no fixed definition of a large primate, so the length of the list is somewhat arbitrary. Primates exhibit the highest levels of sexual dimorphism amongst mammals, with males generally being larger than females within the given size ranges. The size ranges describe typical values and may not include the full extremes among all observed specimens. Mandrills and baboons are monkeys; the rest of the species on this list are apes. Typically, Old World monkeys (paleotropical) are larger than New World monkeys (neotropical); the reasons for this are not entirely understood but several hypotheses have been generated. As a rule, primate brains are "significantly larger" than those of other mammals with similar body sizes. Until well into the 19th century, juvenile orangutans were taken from the wild and died within short order, eventually leading naturalists to mistakenly assume that the living specimens they briefly encountered and skeletons of adult orangutans were entirely different species.
