Apes have a more upright body posture than monkeys, and are often able to walk on 2 legs. Apes have a broad chest. Apes rely on vision rather than smell, and thus have shorter noses than some monkeys. Apes have a large brain to body size ratio compared with other animals.
What superfamily do apes belong to?
Hominoidea
What is a female gorilla called?
A female gorilla does not have a special name based on gender. Only adult male gorillas are identified as “silverbacks,” which refers to the silver line of fur adult mountain gorillas produce after maturity.

What is the dental formula for Old World monkeys?
All Old World monkeys, apes, and humans share this 2.1.2.3 dental formula. This not only sets us apart from New World monkeys and prosimians, but it also reflects the evolutionary closeness of the Old World anthropoid species.
Is a gorilla a Catarrhine?
Catarrhines include gibbons, orangutans, gorillas, chimpanzees, and humans.
Are Platyrrhines color blind?
Studies carried out over the past two decades show that many platyrrhine (New World) monkeys have polymorphic color vision. This condition results from the sorting of allelic versions of X-chromosome cone opsin genes at a single gene site, yielding a mixture of dichromatic and trichromatic phenotypes in the population.
Are humans Haplorhines?
Modern haplorhines are divided into three infraorders: the Platyrrhini, the New World Monkeys; the Catarrhini, the Old World Monkeys, apes and humans; the Tarsiiformes, the tarsiers. The two geographically separated lineages of monkeys are distinguished principally by the shape of the nose.
Are Gibbons Old World monkeys?
Gibbons were the first apes to diverge from the common ancestor of humans and apes about 16.8 million years ago. With a genome that has a 96% similarity to humans, the gibbon has a role as a bridge between Old World Monkeys like macaques and the great apes.
What is the difference between Old and New World monkeys?
The New World monkeys are the platyrrhines (“flat-nosed”), a group comprising five families. New World monkeys have broad noses with a wide septum separating outwardly directed nostrils, whereas Old World monkeys have narrow noses with a thin septum and downward-facing nostrils, as do apes and humans.

Gibbons normally do not pose a threat to humans. Like any animal in the wild, however, they become aggressive when they believe their family or their territory is in danger. They use their booming voices to warn off intruders.
Can Gibbons swim?
Gibbons spend almost all of their time in the treetops of the rainforest. They even sleep there, resting in the forks of branches. Because they are not able to swim, different types of gibbons are isolated in different areas by large rivers.
Why are gibbons not monkeys?
Gibbons are not monkeys. They are part of the ape family and are classified as lesser apes because they are smaller than the great apes. The great apes are bonobos, chimpanzees, gorillas, humans, and orangutans. Gibbons are famous for the swift and graceful way they swing through the trees by their long arms.
Are Gibbons intelligent?
Gibbons are highly intelligent animals. They can recognize themselves in the mirror. Also, they are able to communicate via various songs.
What are baby Gibbons called?
Gibbons are social animals that are active during the day (they are diurnal). They live in small, stable family groups consisting of a mated pair (a male and a female who mate for life) and their immature offspring (juveniles, gibbons less than 7 years old).
Where can gibbons be found?
Gibbons are native to the dwindling rain forests of Southeast, South and East Asia. You’ll find gibbons in Thailand, China, Cambodia, Vietnam, Laos, Myanmar, Bangladesh, India, Malaysia, and Indonesia (including Sumatra, Java and Borneo).
How much do gibbons cost?
How much does it cost to buy a Gibbon? In the illegal wildlife trade, somewhere between $30USD and $40,000USD. This depends on where the animal is sold. It may first be sold for a small amount in its country of origin, then more and more as the trade gets more sophisticated and the animal is smuggled further abroad.
What is a group of Gibbons called?
Gibbons live in small family groups (monogamy). The monogamous social structure is unusual – it occurs in only about 3% of mammals. Groups usually consist of an adult pair and their immature offspring. The group size is 2-6 individuals.
What monkey is the smartest?
Capuchins
Why do gibbons sing?
Singing is particularly important to gibbons, which use loud calls and songs to communicate across the dense jungle. Making gibbons sing on helium may sound strange, but Nishimura said it was a logical way to test how the animals controlled their voices when the vibrations in their voices moved higher.
Is Gorilla an ape?
The gorilla, chimpanzee, bonobo, and orangutan are called great apes in recognition of their comparatively large size and humanlike features; the gibbons are called lesser apes. The great apes are much more intelligent than monkeys and gibbons. All nonhuman apes have been classified as endangered species.
