Whats the size of brain of a crocodile..? Best Answer: It is about the size of a walnut. I could be wrong. The brain size of the average crocodile is pretty small. Crocodiles, like most reptiles, have very small brains.They use about 90% of their brain capacity, unlike humans who use about 10% of their brain capacity. The brain is small but complex, and the senses are well adapted.

Volume of a Human Brain The volume of a human brain, otherwise known as cranial capacity, varies depending on several factors, such as age, environment, and body size. The volume is usually measured in cubic centimeters (cm 3 or cc).Modern humans have cranial capacities from 950 cm 3 to 1800 cm 3, but the average volume of a modern human brain is 1300 cm 3 to 1500 cm 3.Viktoriya Shchupak -- 2001.hile the largest Homo erectus brains were about 1250 ml (2 imperial pints) and modern brains average about 1200–1500 ml in volume, female Neanderthal brains were about 1300 ml and those of males about 1600 ml, extending to 1740 ml in the Amud man.. 1200–1500 cm 3.

- At birth, the brain is 25% of adult size, and head circumference averages 35 cm. Head circumference increases an average 1 cm/mo during the 1st yr; growth is more rapid in the 1st 8 mo, and by 12 mo, the brain has completed half its postnatal growth and is 75% of adult size. Head circumference increases 3.5 cm over the next 2 yr; the brain is 80% of adult size by age 3 yr and 90% by age 7 yr.

Did Humans Really Evolve from Apelike Creatures? The vault of the skull is large in humans because of their relatively large brain compared to apes. Even so, the size of the normal adult human brain varies over nearly a threefold range. These differences in size in the human brain do not correlate with intelligence.

Fascinating Facts You Never Knew About the Human Brain The weight of your brain is about 3 pounds. Your skin weighs twice as much as your brain. Your brain is made up of about 75 percent water. Your brain consists of about 100 billion neurons. There are anywhere from 1,000 to 10,000 synapses for each neuron. There are no pain receptors in your brain, so your brain can feel no pain. There are 100,000 miles of blood vessels in your brain.

Are Whales Smarter Than We Are? Size matters, but it's not everything The largest brain on earth belongs to the sperm whale, the same species as the main character in Melville's yarn. The adult sperm whale brain is 8,000 cubic centimeters.Our brain is about 1300 cubic centimeters. This is equivalent to the difference in engine displacement (the space in the cylinders) of a 1960s VW beetle compared with two and a half Formula One race cars.he frontal lobes of the dolphin brain are comparatively smaller than in other mammals, but the researchers found that the neocortex of the Minke whale was surprisingly thick. The whale neocortex is thicker than that of other mammals and roughly equal to that of humans (2.63 mm).

The Human Brain Physical Facts About the Brain. The adult human brain weights about 3 pounds and the cerebrum accounts for about 85% of the brain. The brain is composed of 40% gray and 60% white matter. The gray matter is made up of about 100 billion neurons that gather and transmit signals while the white matter is made of dendrites and axons that the neurons use to transmit signals. The brain is composted of about 75% water and is the fattiest organ in the body, consisting of a minimum of 60% fat. Humans have the largest brain to body ratio of any animal, and the blood vessels in the brain, if stretched end-to-end, would be about 100,000 miles long.
