That award for the animal has the biggest brain goes to the sperm whale. The average weight of an adult male sperm whale\u2019s brain is 7.8kg compared to 1.4kg for a human\u2019s.<\/p>\n
The sperm whale\u2019s signature shape makes it instantly recognisable, particularly its squarish head that seems disproportionately big \u2013 it comprises up to a third of the whale\u2019s body length.<\/p>\n
However, it\u2019s another component of this vast cranium that historically meant the sperm whale was hunted. The spermaceti organ is filled with a pale, waxy liquid, formerly prized by whalers. It\u2019s believed to be involved in buoyancy control and a sophisticated acoustic sensory system that enables these gregarious whales to relate to their complex, three-dimensional environment, and to form intricate social bonds.<\/p>\n <\/p><\/div> <\/section> Main image: \u00a9 Getty Images<\/em><\/p>\n \u00a0<\/p> <\/body><\/html>\n By BBC Wildlife Magazine Published: Thursday, 17 November 2022 at 12:00 am That award for the animal has the biggest brain goes to the sperm whale.
