Animals with the Highest Cognitive Capacity

Chimpanzees

Chimpanzees are the smartest non-human mammal. 1.23 percent of our DNA is shared with them. They're social, self-aware animals who can use tools, solve problems, and sign with people.

Ravens 

Ravens are the smartest bird, smarter than chimps and dolphins. They can solve problems to get food, play dead to mislead other birds, and speak and mimic better than parrots.

Dolphins

Dolphins can express human-like emotions like empathy, despair, and joy. Self-aware, problem-solving, and tool use make them smart animals.

Elephants

These animals have the world's largest brains. They're not the smartest, but they're smarter than chimpanzees and dolphins. Like dolphins, they can show human emotions.

Pigs

Pigs are gregarious and identify other pigs. They treat stranger pigs like strangers. They may be manipulative to achieve what they want, which I find incredibly human-like.

 Octopus

In the wild, octopuses are highly private. We know most about their intelligence through captivity. They're secretive, intriguing, and potentially smarter than we believed.
