Rhinos(犀牛) are big and can be erous. They are also shy and seldom seen. Once there were hundreds of rhino species, but today there are only five. One ancient rhino called Indricotherium was the largest land mammal that ever lived. It was 5m high at the shoulders, and 8.5m long— twice the size of today’s biggest elephant! The living rhinos are still big, averaging 2-3m long and weighing up to 3,600kg.
To see all five species of living rhino you would need to do a bit of exploring. First you might visit Africa for a look at the white rhino and the black rhino. They live in Africa’s dry woodlands and grasslands. Then you could head to India and Nepal for a look at the Indian rhino. It lives in the high grasslands near rivers, where you have to ride an elephant to find one. Finally you might travel to the rainforests on the islands of Indonesia to see the Sumatran and Javan rhinos. These are the smallest and rarest rhinos in the world and extremely difficult to find.
Most rhinos are gentle and timid (胆小的).They have a bad reputation for being very aggressive, but that may be partly because they get frightened easily. Also, they have poor eyesight. They rely on their strong sense of smell to tell them a stranger is approaching, but if the wind is blowing the wrong way, they may not know someone is there until it’s too late.
Rhinos can be found only in their habitats, which is why habitat destruction has caused rhino populations to decline. As they disappear from certain places, their absence leads to many changes to the landscape. For example, black rhinos in Africa only eat shrubs (灌木) and small trees, pruning (修剪) the plants and limiting their growth. Many other species benefit from this, and as rhinos disappear, so do many other animals sharing their habitat. Bushes and trees take over the land and force species like the antelope to leave in search of food. In a short time the whole habitat has changed.
