Sea cucumber

The pike is a kind of freshwater fish．They are good swimmers and like swimming near boats，waiting to be fed．They have sharp teeth to catch fishes．When they are young，they live in groups．However，when they grow up，they prefer to live alone．

A cuttlefish can swim quite fast，so it is also called rocket（火箭） fish．It has eight arms and two feelers on its head，just around its mouth．It ejects ink （喷墨） when it is in danger．Its meat is delicious，and it is often the first choice for many people．

An octopus has long arms，with which to catch food and protect itself．When it is sleeping，one or two of its arms are still on duty，keeping moving．Once it feels something dangerous，it can wake up at once to take action．

If you want to watch and know something about birds, you must find a good place near the bird nest（巢）.
Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we’d better hide ourselves in a close place to the nest, and it’s better to use binoculars(双筒望远镜).
But how to make a bird nest? A good bird nest must be very fine, strong, thick and comfortable. If you want to make one, please follow these:
a) Each nest must have six boards（木板）. Don’t make the boards too slippery（滑）.
b) Dig a small hole in the front of the nest as a “door”. The “door” is big enough so that birds can fly in or out easily.
c) Make sure the rainwater can’t go into the nest.
d) One piece of the board should be easy to open.

Some people think that all wild animals are danger (1). In fact very few of them will attack a man if he leaves them alone. If you met a lion or an elephant, you would run away. But even a lion will avoid a man unless it is very angry. （2）(狮子和老虎只杀死并吃掉人类) when they have grown too old to catch their usual food. Some animals get frightened if they only smell a man. Some stand and look at him for a while before they run away. Some take no notice at all but quietly walk in another direction. Wild animals only attack a man when they are afraid that he means to hurt their babies, or when they are shot at and made angry.
