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).
Behavior: Sperm whales (Physeter macrocephalus) are the largest of the odontocetes (toothed whales) and the most sexually dimorphic cetaceans, with males considerably larger than females.Adult females may grow to lengths of 36 feet (11 m) and weigh 15 tons (13,607 kg).he sperm whale was listed as endangered throughout its range on June 2, 1970 under the Endangered Species Conservation Act of 1969 (35 FR 8495).
