Worldwide, it is thought that between 100,000 and 200,000 non-human primates are used in research each year, [67] 64.7% of which are Old World monkeys, and 5.5% New World monkeys. [68] This number makes a very small fraction of all animals used in research. [ 67 ]
Although several species lack tails, and their common names refer to them as apes, these are true monkeys, with no greater relationship to the true apes than any other Old World monkeys. Instead, this comes from an earlier definition of 'ape' that included primates generally.
Howler monkeys are also known to occasionally raid birds' nests, chicken coops, and consume the eggs. [14] When in smaller groups (up to twelve individuals) and low rainfall (up to 2,200 mm (87 in)), they are more frugivorous. In larger groups and increased rainfall, frugivory decreases as a result of competition and fast food depletion. [15]

More precisely, they consist of the parvorders Platyrrhini (New World monkeys) and Catarrhini, the latter of which consists of the family Cercopithecidae (Old World monkeys in the stricter sense) and the superfamily Hominoidea (apes – including ...
Primates is an order of mammals, which is further divided into the strepsirrhines, which include lemurs, galagos, and lorisids; and the haplorhines, which include tarsiers and simians (monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial mammals, which adapted for life in tropical forests: many primate ...
A March 1953 article called the monkeys "the most popular animals in the city's small zoo." Simon recalls a smaller, more casual zoo than exists today; residents included a bear, peacocks and, of ...
Old World monkeys are primates in the family Cercopithecidae (/ ˌ s ɜːr k oʊ p ɪ ˈ θ ɛ s ɪ d iː /). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus Papio), red colobus (genus Piliocolobus), and macaques (genus Macaca).
That is about to change, as construction crews hammer away at a $6.6-million expansion that will include a 30-foot high monkey habitat with a canopy trail for primates to swing from and get closer ...
