Giraffe, artiodactyl that thrives in Africa, is the highest land animal that survives in the world. It lives in an African savanna and is a herbivore, eating small leaves and branches. Giraffe life in the wild is about 27 years, and the zoo can live more than 29 years. It is mainly distributed in Africa, South Africa, Ethiopia, Sudan, Kenya, Tanzania and Zambia. This is the national animal of South Africa.
The most striking thing about a giraffe is its neck. Amazingly, he only has seven neck bones like other mammals, but his neck is 2.4 meters long! They are more likely to rotate their necks. However, giraffes are "high risk animals" who prefer to use their necks to get around with other deer, or to show love or fight.
Giraffe's tongue is 50 cm long, in addition to rolling up food, they also use their tongue to clean their nostrils and ears. Many people are curious about the two "horns" on the giraffe's head. In fact, they are a process of calcified cartilage, which is a natural tool for defense and attack. You should know that primitive giraffe horns are very large, so when they are in danger, the ends of their heads are all weapons of attack. This is self defense for environmental needs.
Some people think that giraffes are stupid and never bark. In fact, giraffes not only have vocal cords, they also bark. However, the giraffe's vocal cords are very special, there is a shallow groove in the middle of his vocal cords, which makes it difficult to speak. In addition, vocalization requires the assistance of the lungs, chest and diaphragm. However, because the giraffe's neck is too long and the distance between these organs is too far away, it is difficult to call, they are also rarely called.
Giraffes in a zoo can sleep on their own, but wild giraffes often sleep with their feet, and sleep time is very short, usually only two hours a night! For giraffes, sleep is really difficult. Because their necks are too long, giraffes often rest their heads on branches when they sleep, so as not to strain the neck too much.
