In 2014, a study found for first time that the long-finned pilot whale has more neocortical neurons than any other mammal, including humans ...
Peto's paradox is the observation that, at the species level, the incidence of cancer does not appear to correlate with the number of cells in an organism. [1] For example, the incidence of cancer in humans is much higher than the incidence of cancer in whales, [2] despite whales having more cells than humans.

[12] As with humans, the whale mode of reproduction typically produces but one offspring approximately once each year. While whales have fewer offspring over time than most ...
