| | Giraffes are the tallest animals living on the land, reaching up to 8 m! Though they're tall, giraffes can lower(低下) their head to drink water without any trouble. While they're drinking, the blood doesn't rush to their brains because of a special blood circulation system(循环系统). And their tongues are special, too. Being as long as 50 cm, they can help giraffes catch food high up in the trees. |
| --- | --- |
| | Cats have a special talent — they can almost always land on their feet after they fall from a height. This is because of their righting reflex(翻正反射) which works when cats are in mid-air and stops them falling over. Their ears are also quite special. 32 muscles(肌肉) are in their ears, allowing them to move their ears up to 180° to catch even the smallest sound. |
| | Koalas are special animals from Australia. They eat eucalyptus leaves(桉树叶) as their main food. They have special noses which help them know whether the eucalyptus leaves are bad. This helps them get away from the unhealthy leaves and choose the safest ones to eat. Also, koalas have a relaxing life. They sleep for around 20 hours a day. |
