Dolphins have the highest brain-to-body weight ratio of all cetaceans. [11] Monitor lizards, tegus and anoles and some tortoise species have the largest among reptiles. [citation needed] Among birds, the highest brain-to-body ratios are found among parrots, crows, magpies, jays and ravens. Among amphibians, the studies are still limited.
Cephalopods have large, well-developed brains, [8] [9] [10] and their brain-to-body mass ratio is the largest among the invertebrates, falling between that of endothermic and ectothermic vertebrates. [11] The nervous system of cephalopods is the most complex of all invertebrates.
Mice have a direct brain/body size ratio similar to humans (1/40), while elephants have a comparatively small brain/body size (1/560), despite being quite intelligent animals. [18] Treeshrews have a brain/body mass ratio of (1/10). [19] Several reasons for this trend are possible, one of which is that neural cells have a relative constant size ...
Octopuses (along with cuttlefish) have the highest brain-to-body mass ratios of all invertebrates; [48] this is greater than that of many vertebrates. [49] Octopuses have the same jumping genes that are active in the human brain, implying an evolutionary convergence at molecular level. [50]
The nervous system of cephalopods is the most complex of the invertebrates [14] [15] and their brain-to-body-mass ratio falls between that of endothermic and ectothermic vertebrates. [ 12 ] : 14 Captive cephalopods have also been known to climb out of their aquaria, maneuver a distance of the lab floor, enter another aquarium to feed on captive ...
Brain of the sperm whale, considered the largest brain in the world. Sperm whales have the largest brain mass of any animal on Earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males. [23] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [24]

Since most of the brain is used for maintaining bodily functions, greater ratios of brain to body mass may increase the amount of brain mass available for more complex cognitive tasks. [2] Allometric analysis indicates that in general, mammalian brain size scales at approximately the 2 ⁄ 3 or 3 ⁄ 4 exponent of body mass. [3]
