Top 5 Smartest Animals in the World (2022) Rankings

Top 5 Smartest Animals

1- Chimpanzee

The chimpanzee is also known as a chimp. It is a great ape species that lives in the tropical forest and savannah. Four subspecies have been confirmed and one proposed. The genus Pan includes the closely related bonobo and the chimpanzee.

Chimpanzee

Chimpanzee ( Pan troglodytes), is a species of ape most closely related to humans. The chimpanzees live in tropical forests and savannas in equatorial Africa, from Senegal to Lake Albert in the west and northwestern Tanzania to the east. Although individuals are different in their size and appearance, chimpanzees average between 1-1.7m (3-5.5ft) high when standing upright and about 32-60kg (70-130 lbs). Males are more robust and larger than their female counterparts. The Chimpanzees have a brown or black coat, but their faces are unadorned except for a very short white beard. The skin color is usually white, except for the feet, hands, and face which are all black. Younger animals might have pinkish or whitish faces. The foreheads of older males and women often become bald, while the backs turn gray.

Chimpanzees wake up at dawn and spend their days in the trees as well as on the ground. The most intense feeding time is in the afternoon, after a long midday nap. Chimps move around in trees where they get the most food. They use their feet and hands to move. They can also swing and leap by their arms (brachiate), skillfully moving from one branch to the next. Most movement over a significant distance is done on the ground. Although they can walk upright, chimpanzees are more comfortable walking on their hind legs (knuckle-walking). They usually sleep at night in trees, in nests made of leaves and branches. Although they are not able to swim, chimpanzees can wade in the water. The diet of chimpanzees is mostly vegetarian. It includes more than 300 items, including fruits, berries and leaves, flowers, seeds, birds eggs, chicks, and many insects. Chimpanzees hunt both alone and in groups. They stalk and kill various mammals, including monkeys, duikers, and bushbucks. They may also use medicinal plants to treat certain diseases and expel parasites.

Chimpanzee 2025

After a gestation period lasting about eight months, a female chimpanzee can bear one young at a time. The newborn is approximately 1.8kg (4 pounds) in weight and almost helpless. She clings to her mother’s belly while she moves. The baby rides on the mother’s back from 6 months to 2 years old. At 5 years old, weaning occurs. At 16 years old, males can be considered adults. Females typically begin reproducing at 13 years. However, only two offspring are usually born during their lives. Chimps live for approximately 45 years in the wild, and 58 years in captivity. However, some chimps have lived longer than that. Cheetah, the chimpanzee from Tarzan movies in the 1930s and 1940s, lived for approximately 80 years.

All are part of the same family. A chimpanzee’s home is a group of chimps that is made up of families. These family groups usually have 6-10 members. A chimp community may have up to 100 members. This is due to the many family groups that make up the entire group. Although one experienced male chimp can lead a troop, other troops have several male leaders.

Chimpanzees communicate with their troop using body language, facial expressions, and hand-clapping. A male usually stays in the same community where he was born. Females, however, transfer to other communities when they turn 18.

Chimpanzee 2023

Baby apes. When they turn 12-15 years old, female chimps give birth to their first child. The skin of newborn chimps is pink underneath their dark hair, which later becomes darker as they age. They are very helpless from birth and must remain with their mother until they reach seven years old to survive.

The baby begins to hold onto its mother’s breasts shortly after birth. The baby transfers to its mother’s back later and rides on a piggyback for seven months. A young chimp receives milk from its mother up to the age of three. At age four, it can walk on its own but stays with Mom for several more years to learn all the necessary skills to survive. Mother chimps form a strong bond with their young, which may last a lifetime.


2- Dolphin

A dolphin is an aquatic mammal that belongs to the infraorder Cetacea. The families that include dolphin species are the Delphinidae and Platanistidae as well as Inside and Pontoporiidae. There are currently 40 species of dolphins.

Dolphin 2025

A dolphin is any toothed whale belonging to the mammal group Delphinidae (oceanic dolphins), as well as the Platanistidae or Inside families, which contain river dolphins. Six of the 40 species of Delphinidae dolphins are often called whales. This includes killer whales and pilot whales. The dolphin name is also used for members of the fish family Coryphaena, Coryphaenidae.

The majority of dolphins are small and can measure less than three meters (10 feet) in height. They have simple, needle-like teeth, spindle-shaped bodies, and beaklike noses (rostrums). Although some cetaceans may be called porpoises occasionally, scientists prefer this name to refer to the six Phocoenidae species. All of them have blunt snouts, and spade-like teeth, and are different from dolphins.

Dolphin 2022

Dolphins are well-known for their intelligence, friendliness, grace, intelligence, playfulness, kindness, and gentleness. The common and bottlenose dolphins are the most well-known species ( Delphinus and Tursiops tracts). The bottlenose is a well-known performer in oceanariums because of its “built-in smile”, which is formed by the curvature and shape of its mouth. Because of its intelligence, and ability to communicate using a variety of sounds and ultrasonic pulses, it has been the subject of scientific research. It is more comfortable in captivity than the common dolphin which is shy. The bottlenose dolphin also has the longest social memory among all nonhuman species. Many members of the species were able to recognize individual dolphin whistles after being separated for at least 20 years. In several experiments, bottlenose dolphins were able to recognize their reflections. This suggests that they are self-aware. This ability has been seen only in higher primates, and very few other animals.

You can find dolphins in freshwater or saltwater. They are found in marine environments all over the world, from subpolar to equatorial waters. Both the common and bottlenose dolphins can be found in both warm and cold glasses of water. They can swim at speeds up to 30 km/hr (18.5 miles) in short bursts. Common dolphins are faster. Many species are attracted to moving ships, and will often ride the waves caused by their bows. Many coastal species of oceanic Dolphins spend considerable time in freshwater. River dolphins can live in freshwater up to several thousand kilometers away from the ocean, while some others spend their entire lives in coastal waters. Dolphins are social animals that gather in schools ranging from five to many thousand. All dolphins are carnivorous and eat fish, squid, as well as other invertebrates.

HabitatDolphins can thrive in both warm and colder glasses of water. Dolphin pods have been seen near shore as well as in deeper offshore waters such as the Indian Ocean. Some dolphin groups remain in the same area for their entire lives, while others migrate.

Dolphin

Challenges and ThreatsDolphins worldwide are at risk from a variety of human-generated threats. The two biggest threats to dolphins are entanglement with fishing gear, nets, and pollution. Dolphins may accidentally get caught in nets and fishing gear when they are hunting the same species of fish as commercial fishing vessels. The discarded gear and ropes can also cause them to become entangled, which results in significant marine mammal deaths every year. The human-caused pollution is also causing problems for dolphins. This includes diseases and difficulty finding food.

Maternal HabitsDolphins don’t mate for their entire lives. To attract a mate, dolphins often put on displays that include vocalizations and posturing. Dolphins can gestate for 12 to 18 months. The calves are born tail-first and are cared for primarily by their mothers and any other females.


3- Orangutans

Orangutans, a great ape native to the rainforests in Indonesia and Malaysia, are incredibly rare. While they are currently restricted to Sumatra and Borneo, during the Pleistocene their range extended across Southeast Asia and South China. Orangutans are now classified in the genus Pongo.

Orangutans 2025

Orangutans, a large arboreal mammal known for their distinctive red fur are well-known. They spend most of their time in trees. They can move through the branches thanks to their long, strong arms and strong grasping hands and feet. These intelligent, great apes have 96.4% of our genes.

Orangutan is Malay for “man of the forest”. Orangutans live in solitude in the lowland forests where they live. They eat wild fruits such as figs and mangosteens and drink water from the holes in trees. To sleep at night, they build nests in trees and vegetation. An adult male orangutan can weigh in at 200 pounds. Flanged males are distinguished by prominent cheek pads called “flanges” and a throat sac that is used to make loud verbalizations, called long calls. Unflanged males look like adult females. An unflanged male can become a flanged one, a phenomenon that is unique among primates.

The behavior and appearance of Sumatran and Bornean orangutans are slightly different. Both have reddish-shaggy fur. Sumatran orangutans, however, have more facial hair. Sumatran orangutans are said to be closer in social relationships than their Bornean counterparts. Bornean orangutans tend to be more inclined to move on the ground from the trees than their Bornean counterparts. Both species have seen dramatic population declines. There were more than 230,000 orangutans at the time of the Great Depression. However, the population declines have been dramatic. The Sumatran is estimated to be around 7,500 (Critically Endangered) while the Bornean is currently at about 104,000.

Orangutans

orangutan (Malaysian for “person of the forest”) (genus pongo), also known as orangutan is one of three species of Asian great apes that are found in the rainforests of the Southeast Asian islands Sumatra, Borneo, and Sumatra. Large areas of Borneo are inhabited by the Bornean orangutan, Pongo pygmaeus. The Sumatran orangutan, P. abelii and the Tapanuli (P. Tapanuli orangutan (P. Orangutans have cognitive abilities similar to the gorillas and chimpanzees, the closest primates to humans.

Although they aren’t as strong as the gorilla, orangutans are more powerful than chimpanzees. An adult male can reach a height of 1.3m (4.3 feet) and weigh 130 kg (285 lbs) in the wild. Females are typically smaller at 37 kg (82 lbs) Older males develop wide cheek pads, a unique feature among primates. The skin is usually dark brownish or brownish and covered with a lot of coarse, sparsely colored hair. Some adult males and older females may have partially- or completely bare backs. However, the hair of a male can look almost like a cape when his arms are extended.

Orangutans, the largest arboreal animal, spend more than 90% of their waking time in trees. Most of their day is spent resting or feeding. Orangutans eat mainly ripe fruits, but they also eat more than 400 other types of food. Orangutans build a sleeping platform from the branches and leaves of trees almost every night by breaking and bending twigs, leaves, and branches. Orangutans, unlike African apes, use vegetation to shelter themselves from the rain.

Orangutans 2023

Orangutans spend short periods of their day resting and feeding. They also travel through the forest canopy where they often use all four legs and feet to move. Brachiation allows orangutans to swing through trees with only their arms. Their legs are quite short but their arms are proportionately longer than those of other great apes. Hook-like hands have long fingers with palms that are short and small thumbs. Similar to the hands, the feet have opposable big toes similar to the thumbs. Flexible hip joints, another arboreal adaptation that allows orangutans to move in the same way as humans, allow for similar movement of their arms and legs. Orangutans can be slowed down on the ground so a person can keep up with them. They are not like African apes, who walk with closed fists and extended palms.

Males go through two stages of sexual maturation: subadult and adult. Adult males are larger than subadults and have striking secondary sexual characteristics. These include the prominent and flat cheek pads along the sides of their faces. These pads increase the size of the head and are associated with higher levels of testosterone. The throat pouch of adult males serves as a resonating chamber to produce the “long call”, a series of roars that can be heard up to 2km (1.2 miles). Males usually vocalize for at least one minute. Calls up to five minutes long have been recorded and given the name of the call. The long call is used to attract females, and it serves to spread males apart. Females rarely repeat the entire sequence. Orangutans, on the other hand, are usually silent. Subadult males have smaller cheek pads and a narrower throat pouch. They also don’t long call. Subadult males are smaller than adult males but still larger than adult females. Subadults can remain in this condition for up to 10-20 years. Stress associated with adult males has been shown to cause this retarded development.


4- Elephants

The largest land animal known is the elephant. Three species of elephants are currently known: the African bush elephant and the African forest elephant. They are an informal group within the family Elephantidae.

Elephants

Elephant populations in Asia and Africa have seen a significant decline over the past century. Poaching for illegal ivory trade is the greatest threat to African elephants, while Asian elephant populations face the greatest risk of habitat loss and conflict between human-elephant conflicts.

Elephants are one of the largest land mammals and have large bodies, long trunks, and large ears. Their trunks are used to pick up objects, give warnings, and bathe in water. Male and female African elephants both grow tusks. Each individual can be left- or right-tusked and the one that they use most is often smaller due to wear and tear. Many purposes can be served by elephant tusks. These teeth can be extended to protect an elephant’s trunk, move and lift objects, collect food and remove bark from trees. They can also be used to defend. Elephants can even use their tusks during drought to dig underground water holes.

Elephants 2025

There are two distinct African species, the savanna and forest elephants. They have a variety of traits that distinguish them. The African savanna elephant is the largest species of elephant, while the Asian forest and African forest elephants are comparable in size.

There are more than 10 physical differences between Asian elephants and their African cousins. Asian elephants have smaller ears than the African species’ large, fan-shaped ears. While only some Asian elephants have tusks for males, both African and Asian elephants grow them.

Matriarchs lead elephants into complex social structures that include females and calves. Male elephants, on the other hand, tend to live alone or in small groups of bachelors. After a 22-month gestation period, a single calf is born every four to five years to a female. This is the longest gestation period of any mammal. The entire herd of females related to the calves cares for them. The maternal herd may keep the female calves together for their entire lives. Males will leave the herd when they reach puberty. Forest elephants may have only one adult female and her offspring, but their social groups can be quite different. They may however congregate in larger groups when resources are greater.

Elephants 2026

To survive, elephants require large areas of land to sustain their ecological needs. An elephant can eat hundreds of pounds of plant material in one day and can easily feed for 18 hours. They often become involved in conflicts with other animals as they try to take over their habitat.

The African elephant is the largest land animal in the world. Bull elephants are 3m tall and weigh up to 6,000kg. The average lifespan of wild elephants is 60-70 years. Males reach their maximum size around 35-40 years.

It’s not only adults who are big, but even calves! A baby elephant’s birth weight can be 120kg, which is almost 19 stone.

There are two types of elephants: African and Asian. African elephants have ears that are larger than those of their cousins. They are described as having ears that look like the African continent. Asian elephants, on the other hand, have ears that look like the Indian subcontinent.

Elephants 2023

A trunk difference is also evident: African elephants have two fingers at the tips of their trunks while Asian elephants only have one.

Two types of vocalization can be produced by elephants. They alter the size of their nostrils when air passes through the trunk. Low sounds include the growls, roll-grooves, snorts, and roars. High sounds include the trump and trumpet, pulsated trumpet phrase, bark, and gruff cry. The voice box (larynx), which initially caused rumbling sounds thought to be due to intestinal activity, is now understood to produce them. They are similar to cats purring. Vocalizations are produced in the larynx, which has a special structure called the pharyngeal pocket. The throat of most mammals contains nine bones that are connected in a box-like structure called the hyoid device. This supports the tongue as well as the voice box. The hyoid apparatus is only five bones for elephants. The gap left by missing bones can be filled with muscles, tendons, and ligaments. These looser attachments give the larynx great freedom and allow for the formation of the pouch at the pharyngeal end of the tongue. This unique structure allows for sound production. It also has voluntary muscles which allow the pouch to serve as a resonating chamber, allowing calls at frequencies below human hearing. These low-frequency calls (5-24 hertz), are heard by elephants within a distance of up to 4 km (2 miles). The ground and air carry low-frequency sound waves. Experiments have shown that elephants can also detect seismic waves. Elephants can make a variety of other sounds by beating their trunks against the hard ground, trees, or their tusks.


5- African Grey Parrots

The grey parrot is also known as the Congo gray parrot or Congo African grey parrot. It is an Old World parrot of the family Psittacidae. Although the Timneh parrot was once considered a subspecies, it has been made into a full species.

African Grey Parrots 2025

This medium-sized African grey parrot is a charming companion because of its ability to mimic sounds and talk. Many African grey owners report that their greys can talk in context and can be very sensitive to emotions. The African grey parrot is more than a talker. They are also well-known for their intelligence.

The African grey parrot is one of the most intelligent talking/ mimicking birds on Earth, earning it a great reputation among bird lovers. Bird keepers love this intelligent bird. It’s also a bird that is well-known to novice bird watchers. The African grey parrot is one the oldest species of psittacine, and records of it date back to Biblical times. This parrot is a popular choice because of its simple beauty and no-nonsense approach.

The African grey looks almost like a pigeon at first glance. However, further, inspection reveals that it is a medium-sized and dusty-looking bird. It also has bright red eyes, an intelligent orange tail, and stunning scalloped patterns to its plumage.

African Grey Parrots

The habitats of African grey parrots are savannas and coastal mangroves, woodland, and the edges of forest clearings within their West and Central Africa range. Although the Congo African gray is the largest of the African grey subspecies, it has a wider natural range, which includes the southeastern Ivory Coast and Kenya. The Timneh African gray is found in the Ivory Coast’s western border and southern Guinea. In the wild, they eat mainly palm nuts, seeds, and fruits.

The African grey is often regarded as the symbol of intelligence in parrots. This bird is not only able to memorize a lot but also has a knack for understanding the meanings of words and phrases.

Toys that challenge the intelligence of African greys, like puzzles and foraging toys, are essential. The Nutri-Berries from Lafeber Company are ideal for foraging. This complete food contains a balanced mixture of seeds, grains, and other nutrients. It is shaped like a berry. The Nutri-Berries are a complete food that contains mainly whole grains and seeds. This encourages African greys, who can hold, eat, and play with them. This is similar to the wild foraging of African greys.

Stress and noise in their environment can make African greys feel stressed and anxious. You can help them relax by placing one corner against a wall, as opposed to the middle of a room.

African grey parrots are more prone to deficiency in vitamin-A/beta-carotene and therefore benefit from eating vegetables high in beta-carotene, such as cooked sweet potato and fresh kale. Vitamin-D deficiencies are another concern for greys who have a poor diet. A balanced diet that includes Nutri-Berries pellets is a good option to prevent vitamin and mineral deficiency. A pelleted diet means that a grey does not require vitamin supplements.

Grey’s talking ability is a major reason for its appeal. The grey is one of the most vocal parrots, being able to repeat phrases and words after only hearing them once or twice. The bird attains full speaking ability at around one year old, but most people become proficient mimics much sooner.

African Grey Parrots 2024

Research has shown that greys can develop a remarkable vocabulary and can understand what they are saying. This species is most well-known for its popularity and high profile. Dr. Irene Pepperberg and Alex Pepperberg are the most prominent CAGs. Alex and Dr. Pepperberg were colleagues at Brandeis University for over 30 years until their tragic death in 2007. This was due to an arteriosclerosis-related event (“hardening the arteries”), which led to his untimely passing. Over their three decades of joint research, Dr. Pepperberg taught Alex how to identify and recognize objects, colors, and shapes. Alex was able to understand concepts such as same, different, category, and count objects. Alex was still on the path to more complex thinking processes. His fellow African greys Griffin (AKA “Wart”) and Arthur (AKA” Wart) continue to work with Dr. Pepperberg to get to that point.

Greys may be smart enough to speak rather than scream but it is wrong to assume that they are quiet. Although they aren’t as loud as other South American species, greys can learn to make household sounds and then use them relentlessly, much to the dismay of guardians. Imagine a microwave ringing incessantly or a cell phone ringing incessantly with no option to turn it off.

Two distinct subspecies exist of the African gray parrot: the Congo African Grey ( Psittacus Erithacus Emeracus), also known as the red-tailed, and the CAG and the Timneh African Grey ( Psittacus Erithacus Timneh), or the TAG. The large Congo greys are often called “Cameroons”, as they were once believed to be from the same area. However, the larger birds were smuggled into Cameroon, and that country was listed on their export papers. Because of their large natural habitat, these birds can come in many sizes and shades of grey. The CAG is the same subspecies, regardless of its size or color.

The CAG is larger and has a scarlet tail. It also has a black beak. The TAG is smaller and has a darker, almost black body. It also has a horn-colored, horn-colored beak. The color of its tail can range from maroon to black. Both birds are equally good companions.

African grey parrots will be more readily available at avian-specialty shops or from bird breeders. Sometimes, African greys can be adopted by bird rescue/adoption groups.

African Grey Parrots 2023

You’ve probably seen an African Grey parrot before. They are stunning birds. But did you also know they can learn new words and use them in context? It would be an understatement to say these birds are intelligent. But that’s not all that makes them so unique. Continue reading to learn more about African Grey parrots. This includes information on their origins and the different subspecies. These amazing birds can inspire you to become more involved in conservation, research, and adoption.

The Lowland rainforest is their preferred habitat. They will venture into nearby savannas, mangroves, and agricultural land to find food. They forage in small groups, usually less than 50 birds. This species is mostly frugivorous and eats seeds, nuts, and fruits from many genera, including Bombax and Ficus, and Macaranga. They have a preference for Elaeis guineensis oil palm fruit. It also eats flowers, bark, and other invertebrates such as insects and snails. It can also be seen descending to the ground to get nutrients and anti-parasitic substances. It prefers to climb between the branches with its feet and beak when foraging in trees.

This species is prey to many raptors, such as Palm-nut vultures ( Gypohierax Angolensis). Monkeys take nestlings and eggs. An alerted predator might cause a flock of African greys to fall silent, before suddenly breaking cover and screaming. Wild birds live for about 20 years, while captive specimens can live up to 50.
