It has been suggested that the ideal human figure has its navel at the golden ratio (, about 1.618), dividing the body in the ratio of 0.618 to 0.382 (soles of feet to navel:navel to top of head) (1 ⁄ is -1, about 0.618) and Leonardo da Vinci's Vitruvian Man is cited as evidence. [23]
Giraffe skeleton on display at the Museum of Osteology, Oklahoma City. Fully grown giraffes stand 4.3–5.7 m (14–19 ft) tall, with males taller than females. [46] The average weight is 1,192 kg (2,628 lb) for an adult male and 828 kg (1,825 lb) for an adult female. [47] Despite its long neck and legs, its body is relatively short.
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 ...
Anatomy of the human head. The human head consists of a fleshy outer portion, which surrounds the bony skull. The brain is enclosed within the skull. There are 22 bones in the human head. The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between 2.3 and 5 kilograms (5.1 and 11.0 lb) Over 98 ...
Often mistaken with the southern giraffe, the northern giraffe differs by the shape and size of the two distinctive horn-like protuberances known as ossicones on its forehead; they are longer and larger than those of southern giraffe. Male northern giraffes have a third cylindrical ossicone in the center of the head just above the eyes, ranging ...

A giraffe feeding experience at a Texas wildlife center turned frightening last week when one of the animals hoisted a toddler from the bed of the pickup truck she was riding in.
In okapi, the male's ossicones are smaller in proportion to the head, and taper towards their tips, forming a sharper point than the comparatively blunt giraffe ossicone. Whereas female giraffes have reduced ossicones, female okapi lack ossicones entirely. The morphology of ossicones in the extinct relatives of giraffes and okapi varies widely.
