The great apes are considered to be the smartest creatures after humans. Among them, orangutans stand out as being especially gifted with brain. They have a strong culture and system of communication, and many have been observed to use their tools in forest.
Unsurprisingly, chimpanzees are one of the most intelligent animals on this planet—next to humans, of course. Similar to how humans inherit their intelligence from their mother, a chimpanzee's intelligence also greatly relies on their genes.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
The smartest ones are usually thought to be the troodons, bird-like dinosaurs from the late Cretaceous period. They fit many of the requirements we usually look for in a technologically advanced species. Not only were they intelligent (based on the size of their brains), but they were very social.
Chimpanzees. Chimps are our closest relatives in the animal kingdom, so it's unsurprising they display intelligence similar to that of humans. Chimps fashion spears and other tools, display a wide range of emotions, and recognize themselves in a mirror.

This research has firmly established that chimps are one of the most intelligent species on earth.
BIOLOGISTS have long thought that the chimpanzee was the animal closest in intelligence to the human, but recent work assigns that honour to the dolphin.
The evolutionary process has … no preplanned outcome. Dinosaurs, had they survived (ancestral birds notwithstanding), wouldn't necessarily have evolved great intelligence, but if some did, it probably would be more bird-like than human-like owing to dinosaurs' closer ancestral relationship to birds.
Horses and Dogs are both intelligent animals, but they have different cognitive strengths. Horses excel in areas like navigational intelligence while dogs do better with social intelligence. Neither animal is smarter than the other, that's just what makes them unique!
Scientists have studied both species and their brains to find the answer to this very question. And, scientifically speaking, dogs are likely smarter than cats. The research study looked at the brains of animals in the order Carnivora, a group of mammals containing bears, seals, raccoons as well as cats and dogs.
Pigs are gentle creatures with surprising intelligence. Studies have found they're smarter than dogs and even 3-year-old children! In the wild, pigs form small groups that typically include a few sows and their piglets.
They learn faster than dogs or primates and their intelligence is compared to that of a three year old child. Cows have excellent problem solving skills that involve logic. Once they master how to solve a problem, they celebrate jumping, wagging their tails and running happily.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.
It is believed that squids are slightly less intelligent than octopuses and cuttlefish; however, various species of squid are much more social and display greater social communications, etc., leading to some researchers concluding that squids are on par with dogs in terms of intelligence.
Consisting of two hemispheres, this chunk of neural anatomy is responsible for the animal's cognition (amongst other stuff). Herculano-Houzel estimated that T. rex had roughly 3 billion cerebral neurons packed into its 343-gram (12-ounce) brain; more than the number found in baboons.
“T. rex was probably a pretty agile, fairly intelligent predator, [so] it's nice to have these types of data to support that,” she says.
Dinosaurs didn't have email or text messages to keep in touch, but scientists are quite certain the beasts engaged in dialogue. Those communications likely included hoots and hollers, cracking sounds, dance and song, and even symbolic love calls made with showy plumage.
The capybara considered the friendliest wild animal, has a calm and compassionate nature, even adopting stray and runt animals, and even providing transportation on its back for birds and monkeys.
The encephalization quotient (EQ) (the size of the brain relative to body size) of elephants ranges from 1.13 to 2.36. The average EQ is 2.14 for Asian elephants, and 1.67 for African, with the overall average being 1.88.
Pigs are actually considered the fifth-most intelligent animal in the world—even more intelligent than dogs—and are capable of playing video games with more focus and success than chimps! They also have excellent object-location memory.
Although chickens have a reputation of not being the smartest birds in the nest, the studies indicate that they are on par with other highly intelligent species such as dogs, chimpanzees, elephants, dolphins and even humans, Marino said.
A blue whale can generate a maximum force of approximately 60 kilonewtons. Whales can claim the title of the strongest creature on the planet simply due to their enormous size.
