Some zoologists think that the giraffe's pattern is for camouflage. Many people have reported mistaking a giraffe for an old dead tree. When the tree walked away, they realized that it was a giraffe. 一些动物学家认为长颈鹿身上的花纹是用来伪装自己的。很多人都表示曽把一只长颈鹿看成一棵枯死的老树。当树自己走开了，他们才发现那是长颈鹿。 A giraffe's feet are the size of a dinner plate—12 inches across (30.5 centimeters). 长颈鹿的脚跟西餐用的大盘子差不多大——直径12英寸（30.5厘米）。 Giraffes have the same number of vertebrae in their necks as we do—seven. 长颈鹿的脊椎骨数量跟我们的一样——都是7块。 A giraffe's tongue is 18 to 20 inches (46 to 50 centimeters) long and blue-black. The color may keep the tongue from getting sunburned. 长颈鹿的舌头有18到20英寸长（46到50厘米），颜色是蓝黑色。那样的颜色或许可以保护舌头不被晒伤。 Giraffes can moo, hiss, roar, and whistle. 长颈鹿可以像牛那样哞哞叫，也可以发出蛇那样的嘶嘶声，会咆哮，也会吹口哨。 The record running speed of a giraffe is 34.7 miles per hour (56 kilometers per hour). 长颈鹿的奔跑速度最快纪录是每小时34.7英里（每小时56千米）。 The giraffes at the San Diego Zoo enjoy raw onions as a treat. |
