Brain of the sperm whale, considered the largest brain in the animal kingdom. Sperm whales (Physeter macrocephalus) have the largest known brain mass of any extant animal, averaging 7.8 kg in mature males. [4] Orcas (Orcinus orca) have the second largest known brain mass of any extant animal. (5.4-6.8 kg) [5] Bottlenose dolphins (Tursiops ...
The name "pilot whale" originated with an early theory that pods were "piloted" by a leader. Other common names include the "pothead whale" (after the bulbous melon), and "blackfish" (a catch-all term used to designate numerous species of small, dark-colored toothed whales, including the pygmy sperm whale and false killer whale).
Pilot whales' long, sickle-shaped flippers and tail stocks are flattened from side to side. [4] Male long-finned pilot whales develop more circular melons than females, [4] although this does not seem to be the case for short-finned pilot whales off the Pacific coast of Japan.

The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
The long-finned pilot whale, or pothead whale (Globicephala melas) is a large species of oceanic dolphin. It shares the genus Globicephala with the short-finned pilot whale (Globicephala macrorhynchus). Long-finned pilot whales are known as such because of their unusually long pectoral fins.
A whale died after it became stranded along a stretch of the Lincolnshire coastline. Cleethorpes Wildlife Rescue (CWR) received a report that the pilot whale was stranded near Stallingborough and ...
In some cases, groups of whales strand together. The best known are mass strandings of pilot whales and sperm whales. Stranded cetaceans usually die, because their as much as 90 metric tons (99 short tons) body weight compresses their lungs or breaks their ribs. Smaller whales can die of heatstroke because of their thermal insulation. [citation ...
