You might be wondering why can fishes swim in water but many other animals cannot? Well, it's because they have some special parts which enable them to swim inside water.<br />
<br />
How to describe fish swimming?<b> </b>Well, <b>Fish swim in water with the help of Fins</b>. Unlike most animals, fishes do not have limbs. They rely entirely on their fins for their locomotion. The picture below shows the fins of a fish.<br />

The size and number of fins in any fish can differ from another fish. Generally, fishes of same breed have same number of fins but it can differ. Fishes have streamlined body which helps them swim in water. As you see in the above picture, fishes have different kind of fins. Each of them has their own function. Fins can be in pair or unpaired. Unpaired fins help fishes to maintain balance while swimming. The fin near their tail, called "Tail Fin", helps them move forward, acting like a propeller. Fishes also have pectoral fins which help them to change or maintain direction. Check the animated image below. See how these fishes uses their pectoral fin to change their direction?<br />
