Q 01Which group of monkeys lives mainly in Central and South America and often has prehensile tails?
New World Monkeys
New World Monkeys live in the Americas, and many species, like spider and howler monkeys, have prehensile tails that can grasp objects and support their weight. Old World Monkeys of Africa and Asia do not.
Q 02Which very loud primates have an enlarged hyoid bone that acts as a resonating chamber?
Howler
Male howlers face a trade-off: bigger hyoids come with smaller testes, so the loudest males invest in shouting rather than sperm.
Q 03What is the heaviest monkey species, known for red and blue facial ridges?
Mandrill
The Mandrill is the heaviest monkey: adult males typically weigh 25–35 kg, two to three times a female's weight, and their blue-ridged, red-striped muzzles are unmistakable.
Q 04Which continent is NOT home to any native monkey species?
Australia
Monkeys split into New World (Central and South America) and Old World (Africa and Asia) groups, and neither reached Australia.
Q 05Which of these Old World monkeys is endemic to the island of Borneo?
Proboscis Monkey
The Proboscis Monkey (Nasalis larvatus) is found only on Borneo; its most distinguishing feature is the large, pendulous nose of the adult males.
Q 06Which New World monkeys, the only neotropical primates that frequently use tools in the wild, crack open nuts with stones?
Capuchin Monkeys
Capuchin monkeys position a nut on a flat anvil stone and strike it with a heavier hammer stone, choosing hammers of specific weights for different foods.
Q 07Old World Monkeys typically have nostrils that face in which direction?
Downward
A key anatomical difference between Old World and New World monkeys lies in their noses. Old World monkeys (Catarrhini) have narrow noses with downward-facing nostrils, while New World monkeys (Platyrrhini) have broad, flat noses with widely spaced, sideways-facing nostrils.
Q 08Which dietary label fits most monkey species?
Omnivores
Omnivores they are: menus vary by species but can run from fruit, leaves, seeds and flowers to eggs, insects, spiders and other small animals.
Q 09The rhesus macaque has the widest range of any non-human primate, across which region?
Asia
The rhesus macaque's range runs from Afghanistan through India to northern Thailand, across South, Central and Southeast Asia.
Q 10Which monkey group generally has more opposable, human-like thumbs?
Old World Monkeys
Most New World monkeys lack a truly opposable thumb (some cebids excepted), so the Old World group gets the better grip.
Q 11Which Old World primates have only stubs for thumbs, an adaptation for swinging through trees?
Colobus
Colobus comes from the Greek for 'docked' or 'mutilated', a reference to the missing thumb.
Q 12What is the common collective noun for a group of monkeys?
A Troop
A Troop is the usual collective noun for monkeys; mandrill 'hordes' in Gabon's Lopé National Park have been counted at over 800 animals, among the largest primate groups known.
Q 13Which monkey species is considered the smallest in the world?
Pygmy Marmoset
The Pygmy Marmoset of the western Amazon is the smallest monkey: adults weigh only about 100 grams, yet can leap several metres between branches.
Q 21The golden snub-nosed monkey of China mainly eats which unusual food?
Lichens
Lichens are the golden snub-nosed monkey's staple, often making up the bulk of its diet in the snowy mountain forests of central China, supplemented by leaves, buds and seeds.
Q 22The emperor tamarin's flowing mustache allegedly earned it a name honoring which ruler?
Wilhelm II
Wilhelm II, the mustachioed German Kaiser, is the ruler the emperor tamarin was jokingly named after around 1907; the joke stuck in its scientific name, imperator.
Q 23The golden lion tamarin's entire wild range lies within which Brazilian state?
Rio de Janeiro
Q 14What do macaques and baboons use their internal cheek pouches for?
Storing food temporarily
Old World monkeys like macaques, baboons, and mandrills have cheek pouches that allow them to quickly gather and store food while foraging, to be eaten later in a safer location.
Q 15Which word best describes the lifestyle of most New World monkeys?
Arboreal
New World monkeys are generally more arboreal, meaning they spend most of their time in trees, using their agility and often prehensile tails to navigate the canopy.
Q 16Which monkey species is famous for soaking in hot springs in winter, a habit begun in the 1960s?
Japanese macaque
Japanese macaques at Jigokudani in Nagano took up bathing in the early 1960s, after a young female entered a ryokan's outdoor hot spring; the park later built the monkeys their own pool.
Q 17The gelada, a monkey with a bare red 'bleeding heart' chest patch, lives only in which country's highlands?
Ethiopia
Geladas live only in the Ethiopian Highlands at up to 4,400 m, and they are the last surviving species of a genus once spread across Africa and into Spain and India.
Q 18Which monkey species is known for its strong affinity for water and is considered a good swimmer?
Rhesus Macaque
Rhesus macaques swim readily: in the 1930s a Florida tour operator released some on an island in the Silver River, expecting them to stay put, and they simply swam ashore.
Q 19Digs in Brazil show capuchin monkeys have used stone tools to crack nuts for roughly how long?
About 3,000 years
Hammer stones excavated at Serra da Capivara National Park, Brazil, date capuchin nut-cracking back about 3,000 years, roughly 450 monkey generations; tool sizes changed over time as their target foods changed.
Q 20Which species is generally considered the longest monkey, counting body and tail?
Chacma Baboon
While another species is the heaviest, the chacma baboon is often considered the longest monkey species when body and tail lengths are combined, with adult males reaching up to 45 inches in body length and a tail up to 33 inches.
Rio de Janeiro state holds the golden lion tamarin's entire wild range, in Atlantic Forest fragments around the São João River basin; a 2023 census counted about 4,800 wild animals.
Q 24Golden lion tamarin fur is bright orange yet unusually lacks which pigments?
Carotenoids
Carotenoids produce most bright oranges in nature, so the source of the tamarin's color is a puzzle; its dark face is completely hairless.
Q 25The critically endangered cotton-top tamarin is found in the wild only in which country?
Colombia
Colombia is the cotton-top tamarin's only home, in forest fragments of the country's northwest; tens of thousands were exported for biomedical research before CITES protection in 1976, and only a few thousand remain wild.
Q 26Spider monkeys, which hang by their tails with arms longer than their legs, lack what?
Thumbs
Thumbs are absent or reduced to a nub in spider monkeys, leaving a hook-like hand for swinging; dangling by the prehensile tail with limbs loose gives them their spidery look.
Q 27Space pioneer Miss Baker was bought with 25 other squirrel monkeys at a pet shop in which city?
Miami
Miami: Miss Baker was one of 26 squirrel monkeys bought from a Miami pet shop and trained by the Navy at Pensacola before her May 1959 Jupiter flight with the rhesus Able.
Q 28Able, the rhesus who flew with Miss Baker in 1959, died four days later during what?
Electrode-removal surgery
The cause was a rare cardiac fibrillation under anesthesia; Able is now stuffed and displayed at the National Air and Space Museum.
Q 29Albert II, the first monkey in space in 1949, rode which type of rocket?
V-2
Albert II rode a captured German V-2 launched from White Sands on 14 June 1949, reaching about 83 miles, but died on impact when the capsule's parachute failed.
Q 30Barbary macaques, unusually for monkeys, essentially lack what?
A tail
A tail: Barbary macaques have only a vestigial stub, which is why they were long miscalled 'Barbary apes'; they are the sole macaque species living outside Asia.
