The image is of a sperm whale Physeter macrocephalus.

"Sperm whales have the largest brain of any animal (on average 17 pounds (7.8 kg) in mature males)".^[1]

These sentient whales have the largest brains that have ever existed on Earth.

"Absolute size is the most general of all brain properties [...], and ranges in mammals from brains of small bats and insectivores (weighing less than 0.1 g) to those of large cetaceans (up to 9000 g)."^[2]
