Known as the "Flat-headed Brother" in the water, he can kill crocodiles despite his small size. How on earth does he do it?

The flat-headed brother in the water of life is the "otter". Although he is small, he can kill crocodiles. It's because otters are agile and very smart. And the otter's teeth are so sharp that they can easily bite through even crocodile skin.

First, why is the otter called Flathead Brother.

The name Flathead Brother is mainly called the honey badger on the African savannah, because the honey badger dares to fight with the overlord lion on the grassland. Moreover, the honey badger has thick skin and very strong defensive capabilities. Even if it cannot defeat its opponent, it still maintains a ferocious attitude and stalks the opponent. For this kind of character, people in the world call him "Brother Flathead". Of course, otters are also called "flat-headed brothers in the water" because of this personality, because otters usually look docile, but their fighting ability in the water is very fierce. If an otter dares to challenge the crocodile, one of the overlords in the water, he will naturally be called Flathead Brother.

Second, why do otters dare to eat crocodiles?

Otters can be said to be the natural enemies of most freshwater animals. Otters generally eat fish and live in the water all year round. The most common hunting method for otters is ambush, especially in winter. They often hide in holes in the ice, wait for fish to swim over, and then suddenly spring out to prey. The reason why otters dare to eat crocodiles is because they move very quickly and think very smartly. When an otter is hunting, it will often lurk behind a crocodile. When an otter attacks, it will suddenly jump behind the crocodile and then bite the crocodile's neck, making the crocodile unable to fight back. Of course, otters have sharp teeth, and even with these teeth, crocodile skin can be easily bitten open.

Summarize why the flat-headed "otter" in the water can kill the crocodile. The first is that the otter is very smart, and the second is that it has good teeth.
