单选题根据下面内容，回答题
  We know that many animals do not stay in one place. Birds, fish and other animals move fromone place to another at a certain time. They move for different reasons; most of them move to findfood more easily, but others move to get away from place that are too crowded.
  When cold weather comes, many birds move to warmer places to find food. Some fishes givebirth in warm water and move to cold water to feed. The most famous migration is probably themigration of the fish, which is called "salmon". This fish is born in fresh water but it travels manymiles to salt water. There it spends its life. When it is cold, it returns to its birthplace in freshwater. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leavetheir mountain homes when they become too crowded. They move down to the low land. Sometimesthey move all the way to the seaside, and many of them are killed when they fall into the sea.
  Recently, scientists have studied the migration of a kind of lobster. Every year, when theseason of bad weather arrives, the lobsters get into a long time and start to walk across the floor ofthe ocean. Nobody knows why they do this, and nobody knows where they go.
  So, sometimes we know why humans and animals move from one place to another, but at
other times we don't. Maybe living things just like to travel.
