The gyrencephaly index (GI) for humans is 2.2; for bottlenose dolphins is 5.62, and for orcas is 5.70. This makes orcas the most gyrified brain in the world.
Are dolphins more intelligent than whales?
Although dolphins use simple tools and possess unique abilities that are usually only present in complex animals, they still aren’t at the same level of tool usage, problem-solving, and overall intelligence as us. And yes, whales may have larger brains, but that doesn’t particularly mean they’re smarter.

How smart are orcas?
Orcas’ brains are 2 1/2 times average — similar to those of chimpanzees. But scientist think that looking just at the brain-body ratio seriously underestimates the thinking power of larger marine mammals. In other words, orcas might be even much smarter than the size of their big brain suggests.
Are orcas smarter than sharks?
Not only are orcas much bigger, they are also smarter. Great whites are now known to be warm blooded but orcas still have much higher metabolic rates because they breathe air.
What animal has the highest IQ?
CHIMPANZEES
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.
What is a dolphins IQ?

What is the 2nd smartest animal?
Dolphins
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
Do dolphins have high IQ?
Based on current metrics for intelligence, dolphins are one of the most intelligent animals in the world. While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts.

Is a orca the smartest animal?
Experts on marine mammals say that dolphins – including “killer whales,” which are more properly called orcas – rank among the most intelligent species on the planet.
Do orcas eat dolphins?
Looking at all populations, orcas are generalist eaters, consuming fish, seals and sea lions, dolphins and porpoises, sharks and rays, large whales, cephalopods (octopods and squids), seabirds and more. However, some orcas specialise on specific prey, and it turns out orcas are picky eaters!
Do orcas get along with dolphins?
Dolphins rival orcas at an average of 27 mph, proving to be a formidable racing opponent. Orcas are the only predators of white-sided dolphins in the northern Pacific, but not all of them. In 2019 a group of researchers observing dolphins at play noticed a large pod of orcas hanging out dangerously close.
Who is the king of the ocean?
Killer whales
But the true ruler of the sea is the killer whale. Killer whales are apex predators, which means they have no natural predators. They hunt in packs, much like wolves, which are also at the top of their food chain.
What is orca afraid of?
Selbmann says that in the majority of the interactions documented around Iceland, killer whales seem to avoid pilot whales. Occasionally things will get heated and the pilot whales will chase the killer whales at high speeds, with both species porpoising out of the water. Don’t miss what matters.
What can beat an orca?
Orcas are apex predators, which means they’re at the very top of the food chain and they have no predators. Killer whales are some of the largest and most powerful animals in the ocean, and no other predator is able to challenge them.
What is the lowest IQ score ever?
0/200

What is the IQ of a jellyfish?
Jellyfish have no brains at all, so they do not even have an IQ.
Who is smarter cats or dogs?
Though this data might seem to suggest that dogs are twice as intelligent as cats, a direct correlation between larger brain size and increased intelligence has not been conclusively proven. Regardless, dogs’ higher neuron count is often viewed as a gauge of their superior intelligence.
What is the IQ of human?
IQ tests are made to have an average score of 100. Psychologists revise the test every few years in order to maintain 100 as the average. Most people (about 68 percent) have an IQ between 85 and 115. Only a small fraction of people have a very low IQ (below 70) or a very high IQ (above 130).
What was Einstein’s IQ level?
Albert Einstein
Albert Einstein was a German-born theoretical physicist and philosopher of science whose estimated IQ scores range from 205 to 225 by different measures.
