The largest Alaska moose was shot in western Yukon in September 1897; it weighed 820 kg (1,808 lb), and was 2.33 m (7.6 ft) tall at the shoulder. [7] While the Alaska moose and the Asian Chukotka moose match the extinct Irish elk in size, they are smaller than Cervalces latifrons, the largest deer of all time. [8]
The heaviest land mammal is the African bush elephant, which has a weight of up to 10.1 t (11.1 short tons).It measures 10–13 ft at the shoulder and consumes around 230 kg (500 lb) of vegetation a day.
Eastern moose are the third largest subspecies of moose only behind the western moose and the Alaska moose. Males stand on average 1.7–2.0 m (5.6–6.6 ft) at the shoulder and weigh up to 634 kg (1,398 lb). Females stand on average 1.7 m (5.6 ft) at the shoulder and weigh on average 270–360 kg (600–790 lb).
Male Western moose stand anywhere from 1.9 to 2.0 metres (6.2 to 6.6 ft) at the shoulder. Their antlers span 1.5 to 1.7 metres (4.9 to 5.6 ft) and they weigh anywhere from 380–720 kilograms (840–1,590 lb). Female Western moose stand at 1.8 metres (5 ft 11 in) on average, and weigh anywhere from 270 to 360 kilograms (600 to 790 lb).
• The elephant silhouettes are redrawn primarily from a photo by Ian Sewell, [4] with the female modified based on information and photos on Elephant Voices Blog. [5] [6] Newborn silhouette drawn from multiple images found online. • Humans scaled to 170 cm (5 ft 7 in) and 160 cm (5 ft 3 in) respectively.
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 ...
Large mammals develop at an absolute slower rate compared to small mammals. Thus, the large mammal tend have longer gestation periods than small mammal as they tend to produce larger neonate. [18] Large mammals require a longer period of time to attain any proportion of adult mass compared to small mammals. [19]
In men the average weight is about 1370 g and in women about 1200 g. [4] [contradictory] The volume is around 1260 cm 3 in men and 1130 cm 3 in women, although there is substantial individual variation. [5] Yet another study found that adult human brain weight is 1300–1400 g for adult humans and 350–400 g for newborn humans.
