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).
Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 34 metres (112 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature on earth.dontocetes feed largely on fish and squid. A few, like the sperm whale, feed on large invertebrates, such as giant squid. Grey whales are specialized for feeding on bottom-dwelling molluscs. Male whales typically mate with multiple females every year, but females only mate every two to three years.
