With eyes located on the sides of the head, the giraffe has a broad visual field from its great height. [50]: 85, 102 Compared to other ungulates, giraffe vision is more binocular and the eyes are larger with a greater retinal surface area.

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.
Cephalopod (like in octopuses and squid) and vertebrate eyes are both lens-camera eyes with much overall similarity, yet are very unrelated species. A closer examination reveals some differences including embryonic development, extraocular muscles, number of lens parts, and the lack of a retinal blindspot in the cephalopod eye. [162] [163]
Giraffe necks do more than help them reach high leaves in trees. They can keep a lookout for predators, but there is another reason they may have such long necks.
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 ...
There are approximately 117,000 wild giraffes around the world, per the Giraffe Conservation Foundation.This number has decreased by nearly 30% since the 1980s. Meanwhile, the population of ...
Although the okapi has striped markings reminiscent of zebras, it is most closely related to the giraffe. The okapi and the giraffe are the only living members of the family Giraffidae.
