The colours seem just a little out, there's some distracting blurry grass in the extreme foreground, the grass around the giraffes is a bit too long obscuring a bit too much of their legs, and the long grass and shadows make it hard to tell whether the giraffe at the right in particular is a male (which is very relevant for this photo which is ...
The sauropods and giraffes independently evolved long necks. [72] The horned snouts of ceratopsian dinosaurs like Triceratops have also evolved several times in Cenozoic mammals: rhinos, brontotheres, Arsinoitherium, and Uintatherium. [73] Rhynchosaur teeth resemble that of the extant rodents.
The giraffe's head and neck are held up by large muscles and a nuchal ligament, which are anchored by long thoracic vertebrae spines, giving them a hump. [17] [62] [35] Adult male reticulated giraffe feeding high on an acacia, in Kenya. The giraffe's neck vertebrae have ball and socket joints.
The okapi and the giraffe are the only living members of the family Giraffidae. The okapi stands about 1.5 m (4 ft 11 in) tall at the shoulder and has a typical body length around 2.5 m (8 ft 2 in). Its weight ranges from 200 to 350 kg (440 to 770 lb). It has a long neck, and large, flexible ears.
Giraffes are peaceful animals and rarely harm humans. They are not aggressive by nature, and like the giraffe in this video, they main defense mechanism is using their strong legs to kick.
