The crocodile is a kind of reptile that we are familiar with. We can often see them in some movies and TV plays. The real crocodiles we see are generally crocodiles living in zoos. Crocodiles have some outstanding appearance characteristics, which are very obvious when observing them. For example, they have a tail, and it's a very big, very long tail. Another example is that they have a thick layer of scales on the surface of their body to protect their body.
1. Swimming: Crocodiles can not only crawl on land, but also swim in the water. When crocodiles swim in the water, the tail can play a more important role. The tail can provide a lot of power, just like the oars we use when rowing. They also use their tails when they want to change direction in the water.
2. Predation: The tail plays an important role in crocodile predation. When crocodiles encounter some terrestrial animals drinking from the river, they may use their tails to sweep them into the water and then use them as food.
3. Balance: Crocodiles' tails can also help them maintain their own balance. The tail keeps them in balance, both on land and in the water.
4. Turn over: As the crocodile is relatively large, it is also relatively heavy. When they turn over, they need the help of their tails, which can play a supporting role at this time.
5, preserve fat: Crocodile's tail is relatively large, but also play a role in preserving fat. Especially when crocodiles hibernate, they will not eat for a long time, at this time they can consume the fat on their tails.
6. Attack and Defense: Crocodiles also use their tails when fighting other animals or their own kind. The tail can play an important role in both attack and defense.
