Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
Thus, large whales have very small brains compared to their weight, and small rodents like mice have a relatively large brain, giving a brain-to-body mass ratio similar to humans. [4] One explanation could be that as an animal's brain gets larger, the size of the neural cells remains the same, and more nerve cells will cause the brain to ...
Size comparison with a human. Unlike most squid species, the colossal squid exhibits abyssal gigantism, as it is the heaviest living invertebrate species, reaching weights up to 495 kg (1,091 lb). [3] For comparison, squids typically have a mantle length of about 30 cm (12 in) and weigh about 100–200 g (3 + 1 ⁄ 2 –7 oz). [10]
English: Comparison of the size of a human (on the right) and two western gorillas (Gorilla gorilla) (left and middle). The human has an assumed height of 175 cm (5 ft 9 in), while the standing gorilla is 160 cm (5 ft 3 in). The gorilla on the left 120 cm (3 ft 11 in) is in a normal posture with knuckles on the ground.
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
