That’s science. They had 85 billion neurons, according to Suzana and Kaas’ estimate. But how do they manage to breastfeed underwater? "We found that on average the human brain has 86 billion neurons. Sperm whales have 40 to 52 cone-shaped teeth, up to10 to 20cm (4 to 8in) long, in their narrow lower jaws only. The number of neurons in the brain of a sperm whale has not yet been measured - but based on calculations that extrapolate from the brains of smaller whales, their neocortex is expected to have about 2.5 times as many neurons as are found in humans. So I´m going to write about neocortex neurons. Over millions of years, their bodies, brains, sensory systems and intelligence have evolved and adapted for living rich and varied lives in water. Whales have two flippers on the front, and a tail fin. Researchers who studied 28 bird species found that songbirds and parrots can have as many, and sometimes more, neurons packed into their brains than mammals - even monkeys and apes. The number of neurons and their relative abundance in different parts of the brain is a determinant of neural function and, consequently, of behavior. Humans have approximately 100 billion neurons in whole nervous system but is the neocortex the part of the brain responsible of conscience and the more complex cognitive abilities. Very rarely, a female narwhal will grow a tusk or a male will grow two tusks. Not all animals have neurons; Trichoplax and sponges lack nerve cells altogether. Neurons may be packed to form structures such as the brain of vertebrates or the neural ganglions of insects. The whale with the biggest full set of teeth is the sperm whale. Bernd Jendrissek 19:38, 6 … [citation needed] Dentition Edit. Doubt you can do the Samuel? And not one that we looked at so far has 100 billion. These flippers contain four digits. Although whales do not possess fully developed hind limbs, some (such as sperm whales and baleen whales) possess discrete rudimentary appendages, which may even have feet and digits. Toothed whales, such as the sperm whale, possess teeth with cementum cells overlying dentine cells. A neuron, neurone (old British spelling) or nerve cell, is an electrically excitable cell that communicates with other cells via specialized connections called synapses.It is the main component of nervous tissue in all animals except sponges and placozoa. By Mind ... Just how smart are whales? Plants and fungi do not have nerve cells. Even though it may sound like a small difference the 14 billion neurons amount to pretty much the number of neurons that a baboon brain has or almost half the number of … They also have a more sophisticated way of communicating than humans. Most species have a dorsal fin. Whales can project images through sonar to other whales. Are Whales Smarter Than We Are? With the help of bioanthropologist Walter Neves, from USP, Lent expanded the projection to include other species of primates that belong to the super-family of hominids and calculated that the Neanderthals may have had 100 billion neurons (see infographic above). According to reference [2], whales and elephants have on the order of 10 billion neurons, not 200 billion as listed in the table. In particular, the long-finned pilot whale has almost twice as many neocortical neurons as humans (Pakkenberg and Gundersen, 1997). The need for milk is an essential part of the development of any young mammal, and being aquatic makes breastfeeding considerably harder. Why do they have such big brains?
