Orangutans have a huge appetite and sometimes spend an entire day sitting on a fruit tree devouring them. About 60% of its food is fruit—there are hundreds of varieties of fruit, ripe or not; Apes like to eat fruits whose flesh is rich in sugar or fat. Where figs grow, orangutans will eat this mild fruit as their main food, as it is abundant and easy to obtain and digest.
Orangutans also often eat leaves and twigs, invertebrates, and occasionally mineral-rich soil; They also occasionally eat vertebrates, such as slow loris. When ripe fruit is lacking, they eat seeds, or the bark of trees or vines. Especially when the fruit is poor, their strong tooth system brings them great benefits.
When juicy fruit is lacking, they drink the water from the hollow of the tree; This ape will dip one hand into the water and then suck the water that runs down from the hair on the wrist.
In some swamps in Sumatra, orangutans make stick-like tools to remove seeds from the prickly lisa fruit. They also use tools to dig up honey in beehives or termites in tree holes. All members of the population that use tools have this skill, but they use tools differently.
An interesting comparison is that members of other populations do not have this ability, even if they are separated by a river from the tool-using orangutan population. The local tradition of using the tool is very similar to that of wild chimpanzees.

。Among primates, the body size is second only to that of gorillas, with males being larger than females and males being meters long.
Female m Weight Male 75 100 kg Female 40 80 kg Both arms are very long.
Open and wide up to a meter When standing, the arms hang down to the ankles The legs are short and not as thick as the arms Body hair is sparse Dark reddish-brown The shoulders and back have more than 20 cm long hair The forehead is protruding The mouth is protruding Thin lips The eyes and ears are small The nose and nose are small The distance between the eyes is narrow The face of the adult male has a leaf-like thick flesh pad There is an air sac under the flesh leaf It is connected to the larynx It bulges very well when inflated It plays a resonant role when making a voice Some have a beard under the chin Hands and feet are narrow and long The arms and hands are thick and powerful The hands are about 28 cm long.
The feet are about 32 cm long and the canines are well developed.
32 teeth The tooth type is the same as that of humans. Tailless. There are two subspecies found in Kalimantan and Sumatra.
It is the only orangutan species found in Asia with a small range. Not much. Inhabits tropical rainforests.
Males live alone, females live alone, orange oaks, or with baby orangutans. Daytime activity: Part of the time is spent foraging, eating figs, rambutan, mangoes, honey, eggs, young birds, crustaceans, fresh vegetables and plant shoots. The gestation period is 8-9 months.
1 litter per litter Lifespan 25-40 years. The activity is not as fast and agile as the monkeys, and they move their bodies by grasping branches with their hands. Able to walk upright on the ground, but with the support of the fingers of the fists, not the waist. Strong arm strength except for tigers and leopards.
No other predators. Nest with branches on a tree branch 8 12 meters above the ground, cover it with leaves, and sleep on the tree at night. Usually sexually tame and terrible when angry on the side.
Cover your body with large leaves on rainy days. Due to the hunting of female animals and the exploitation of forests, the number is scarce. Many orangutan fossils have been found in Pleistocene strata from southern China to Kalimantan and Sumatra.
Most are single teeth. Judging by the preservation of fossils.
The northern boundary of the orangutan range gradually shifted southward throughout the Quaternary. Miocene Siva Australopithecus found in China, Pakistan and India share many properties with Pleistocene orangutans.
They should be very closely related.
Many scholars even believe that Siva Australopithecus can be regarded as the direct ancestor of modern orangutans. Do orangutans have dry scales? Orangutans belong to the same family (hominidae) as humans, gorillas, and chimpanzees, and you think humans have scales, but of course they don't.

Large, docile, and gregarious, led by a male giant gorilla with a silver back. Likes to sleep on the ground with a nest made of branches, and makes a new nest every day. Walk at least 1 kilometer a day and eat young shoots and green leaves.
Characteristics: Orangutans are very similar in body shape to long-lived animals that have long lived and reproduced in humans.
1. They are very independent individuals, especially the great chimpanzees living in Borneo. Adults almost always move and eat alone. Their offspring gradually become more independent after weaning.
Male orangutans usually disconnect from their mothers after puberty, but females often return.
2. There will also be a certain relationship between animals, they know that there will be a leader in unity, so there is a scientific basis for the statement that Australopithecus is the earliest human. Orangutans recognize and form social relationships with each other orangutans that often overlap with their field of activity. Female orangutans give preference to certain orangutans, and this relationship is also synchronized with reproduction.
Although juvenile males occasionally bond with each other, males are more competitive in their relationships.
3. They also understand the survival of the fittest and the survival of the fittest. The desire to survive is also very strong, and it can be said that it is the best in the animal kingdom.

Orangutans mainly eat fruits (such as durian, rambutan, jackapple, lychee, mango, inverted twister, fig), twigs, flower buds, insects, and creeping plants;
Bird eggs and small vertebrates are also occasionally eaten. Bananas, leaves and twigs, invertebrates, mineral-rich soil, vertebrates, seeds, bark of trees or vines, drinking water from tree cavities, honey, termites, etc.
Orangutans are long-lived animals that grow and reproduce slowly, and their leisurely life history may have been adapted to living in low-mortality habitats, as well as to survive periods of food scarcity. Due to their habits, the density of orangutans is usually very low (only one per square kilometer), especially in fertile river valleys, especially in swampy forests.

In the wild, gorillas feed on leaves, bamboo shoots, vines, wild celery and other succulents, and also hunt some insects to a small extent. In the zoo, gorillas eat about 17 kilograms per day. The recipes are rich in vegetables such as celery, cabbage, plantain leaves, cucumbers, leaves, apples, raw pears, oranges, bananas and other fruits.
Gorillas are also believed to be fruit-eating (eating fruit for their livelihood), but recent studies have shown that at least chimpanzees attack and kill small animals. Studies have shown that the difference in DNA between gorillas, chimpanzees and humans is less than one percent, which is less than the difference between different species of horses. The digestive tracts of gorillas, chimpanzees and humans are almost identical.
These higher primates, gorillas and chimpanzees, are considered herbivores and occasional carnivores. They mainly feed on fruits and vegetables, but they also eat eggs, insects, lizards and other small animals if they are in front of them or if they are very hungry.
-
What gorillas eat depends on what kind of habitat they live in, as well as the season. Mountain gorillas eat mostly greenery, lowland gorillas eat many fruits. There are only a few kinds of juicy fruit that can be obtained during the dry season, so gorillas eat more grass and bark at this time.
Generally speaking, the fruit grows on trees, and gorillas of all ages climb trees to pick the fruit. Western gorillas eat a higher proportion of fruit in their diets than leaves, stems, hearts, and shoots of plants, yet they eat much less fruit than chimpanzees and orangutans.
The western gorilla has a very wide diet with about 200 plant species. But the mountain gorillas inhabited by the Virunga volcano eat only 38 plant species.
It is estimated that an average male adult gorilla eats 30 kilograms of plants per day, and a female adult gorilla eats 18 kilograms per day. In order to be able to handle so much food, gorillas have very strong chewing muscles, and their teeth are very similar to those of humans, except for the long, pointed fangs of male gorillas. The main reason why males have such long tusks is to win in battles.
In addition to plants, gorillas also occasionally eat soil, probably because they contain minerals that are lacking in plants, or because these minerals can neutralize toxic components in food.
While gorillas do not hunt large animals, they will occasionally eat small animals. However, the proportion is very small, accounting for only a weak proportion of the total amount of food. 6%+ of the chimpanzees' food are animals.
-
Gorillas feed on succulent plant stems as their staple diet and hardly hunt other animals. Chimpanzees are mainly omnivorous, feeding on fruits, leaves, eggs, and small animals. The staple food of the orangutan is vegetarian, such as fruit, leaves, bamboo shoots, etc., also eat bird eggs, and the fruit is particularly fond of durian.
The chimpanzee staple food is omnivorous, feeding on fruits, twigs, eggs, and small animals.
The staple food of gorillas, chimpanzees, orangutans, and chimpanzees is bananas.

Orangutans are outgoing and social and live mainly in the tall and lush deciduous forests of central and western Africa.
Orangutans are primates, suborder eumonkeys, and narrow-nosed monkeys. In this sense, orangutans are a type of monkey. But to elaborate, the orangutan is a kind of ape superfamily under the order Primate, the suborder of true monkeys, and the narrow-nosed monkey suborder, so it is not a type of monkey. >>>More
