We all know that animals have brains. But what if we could compare their brains to one another? How would they stack up? By looking at these animals’ intelligence levels and life spans, we can get an idea of how heavy or large their brains are, and which ones are among the smartest:

The animal with the heaviest known brain is the fin whale.

The animal with the heaviest known brain is the fin whale. The fin whale’s brain weighs about 8.8 kg (19 lbs), which is 1.2 times heavier than an average human brain.

In addition to having a huge head, this enormous marine mammal has other features that make it easy to recognize: massive flippers and a long dorsal fin on its backside. You may also see its blow hole when it surfaces from under water!

The animal with the largest brain overall is the sperm whale.

The animal with the largest brain overall is the sperm whale. The average size of their neocortex and cerebellum is greater than all other creatures, including humans, who have much smaller brains overall. However, when you look at how much of an animal’s body weight is made up by its brain (a measurement known as “encephalization quotient” or EQ), humans rank first with an EQ score of 7; whales have an EQ score of just 0.5-1! This means that while sperm whales have larger brains than any other species, they use their mental capacity less efficiently than other animals do.

Sperm whales’ large neocortexes allow them to process information quickly but also makes them more susceptible to damage from toxins like mercury or lead; these are common pollutants found in ocean waters near industrialized areas such as those along North America’s east coast where many sperm whales live

The animal with the largest cerebral cortex in humans.

You might be surprised to learn that the animal with the largest cerebral cortex is humans. The neocortex is the outer layer of gray matter in your brain, responsible for higher cognitive functions such as language, abstract reasoning and consciousness. It makes up 80% of your brain’s mass–and we have more of it than any other creature on Earth!

The neocortex accounts for 20% of our total body weight (compared with just 2% for gorillas). This means that when you’re standing upright on two legs like a human does every day–instead of walking around on all fours like other apes do–you’re carrying around twice as much weight on top as they are at any given time!

The animal with the largest neocortex, or outer layer of gray matter in the brain, is humans.

The animal with the largest neocortex, or outer layer of gray matter in the brain, is humans. The neocortex is responsible for higher cognitive functions like language and reasoning. It also makes up about 80% of our total brain weight–a lot more than any other mammal.

The second-largest animal brain belongs to an elephant’s 3-foot long hippocampus (the part of your brain responsible for memory). This structure weighs in at around 10 pounds on average!

The animal with the longest life span is a tortoise, which lives up to 150 years old.

Tortoises are also slow moving and can live in places where predators are less common. This makes them much safer than other animals that have shorter lifespans and move faster, such as rabbits or deer.

A giraffe has an immense neck and head, which makes it one of the tallest animals on earth.

If you’re interested in learning more about the largest animal brains, we’ve got you covered. The giraffe has an immense neck and head, which makes it one of the tallest animals on earth. In fact, their average height is 6.6 feet tall! Giraffes can weigh up to 2,400lbs (1,100kg).

A cow can produce over half a gallon of milk each day.

The average cow weighs about 1,500 pounds and stands about 5 feet tall. A cow’s brain is about three times larger than that of a human’s, but it weighs only 2% as much because the animal has so much more body mass to support its head. The world record for the most milk produced by a cow in a single day is 10,435 pounds–but this number is dwarfed by what some cows have been known to produce over their lifetime: an average of 20 gallons per day!

These animals have large brains

• Cow: The cow has a large brain and is one of the most intelligent animals.
• Giraffe: The giraffe has an immense neck and head, which makes it one of the tallest animals on earth. Its long neck allows it to reach leaves that are out of reach for other animals, giving them an advantage over less adaptable prey when food is scarce.
• Tortoise: A tortoise’s life span can be up to 150 years!

In conclusion, these animals have large brains. I hope you enjoyed learning about the brains of different animals!
