Hippos are herbivores, but their sparse tusks are ten centimeters long.

Female hippos are extremely aggressive when it comes to protecting baby hippos.

Hippos move in pairs or small groups, and older males often move alone.

They sleep or rest in or near rivers almost all of the day, and come out to eat at night, sometimes swimming more than 30 kilometers down the river to feed.

Hippos feed mainly on aquatic plants, occasionally on land crops, mainly grasses, sometimes go to the fields to eat crops, and when food is scarce, they also eat meat.

Hippos are large in size, but they are light to walk in water.

In the hot sun, muddy water on the surface of the body is more protective from the scorching sun.

The sweat glands of hippopotamus skin secrete a red liquid that acts as a natural sunscreen to moisten the skin, which is often mistaken for blood that is discharged, called "blood sweat".

Because its skin is very sensitive and will dry out after being out of water for a long time, it spends most of the day lazily in the water, relying on the help of water to regulate its body temperature and prevent its skin from drying out, and sleeping on the shore at night.

Their eyesight is so poor that they can't see even above the surface, but this doesn't affect their lives, as the water is often so cloudy that they can't see far at all.

Hippos like to live in groups, led by females, 20-30 in each herd, sometimes as many as 100 or more, especially in densely populated areas, with an average of one per 5.5 square meters.

They have a special set of flexible musculature that uses valves to close their ears and nostrils when diving, and can last about 5-10 minutes per dive, but they are not physiologically adaptable to water like aquatic mammals, and they live on land for a long time, running at speeds of up to 20 kilometers per hour, so they can only be considered semi-aquatic animals.

In normal times, the hippopotamus will submerge its whole body in the water, and only expose its ears, eyes and nostrils to the surface of the water, so that it can not only breathe normally, but also detect danger in time without being detected by the enemy.

In addition to being safe and cool, water also helps them support their large and heavy bodies, allowing them to walk freely in the water.

Although the hippopotamus always stays in the water, it cannot swim and can only dive.

When frightened, they generally avoid water.

Hippos spend most of their time in the water every day, and generally breathe with their heads out of the water every 3 to 5 minutes when they are lurking underwater, but they can lie dormant for about half an hour without coming out of the water to breathe.

Hippos are usually quiet, but once they lose their temper, they often fight, each using their sharp teeth to stab each other's thick skin.

In the past, Yang Wu did not dare to challenge the hippopotamus, because at that time his body was small, and his teeth and claws were not very long and sharp, and he could not hurt the hippopotamus's skin.

But now it's different, since Yang Wu and the elephant crossed the line, he found that it was the same thing.

He can beat elephants one-on-one, so he has lost his awe for hippos.

The reason why Yang Wu didn't provoke hippos before was also because of the animal world he had seen in his previous life.

The animal world of that issue was about the battle between lions and hippos.

A group of female lions went to hunt a hippopotamus that came ashore, some of them bit the hippopotamus's legs, and some jumped on the hippopotamus's back, but they could only cause some skin trauma to it, and they were dragged back to the river by the hippo for a few hundred meters.

The female lions had no choice but to helplessly watch the hippos that entered the river show off their might, and also released their big move against the lions - throwing gong!

As the name suggests, throwing gong is the tail flicking when the hippopotamus poops.

The reason why hippopotamus poop has to flick its tail is to spread the feces farther, which is also a way to mark the territory.

The main purpose of this method of excretion is to claim one's own territory, especially when the territory of the male hippopotamus is threatened from outside.

Male hippos will excrete small hill-high piles of feces near their territory, and they will use this method to deter male hippos or other large creatures from trespassing on their territory.

In the body language of the hippopotamus, while the butt squirts out the feces, the small tail rotates like an electric fan, which will throw the feces far away, and there is also a detail that the hippopotamus urins backwards, just like a high-pressure faucet, which can spray the poop farther, in order to express the power and power of the male hippopotamus.

The male hippopotamus easily escaped from the siege of a herd of female lions, and he seemed very excited and couldn't help but start provoking the lions.

In Yang Wu's mind, no matter how good the hippopotamus is, it can be compared to an adult male elephant?!

So, today the hippopotamus was also added to his food list.

Because the eyesight of hippos is not very good, when Yang Wu was a hundred meters close to them, they had not yet noticed it, and they were still playing freely.

It is estimated that even if they find Yang Wu, they will not take it seriously, and a juvenile male lion cannot threaten them.

Just when Yang Wu walked to the lake, less than thirty meters away from the hippopotamus, they finally found Yang Wu.

"Ang~!ang~......"

There are baby hippos in the hippopotamus herd, and the female hippopotamus can become very aggressive.

They moved some distance from the water to the shore, their mouths the size of basins and howling and intimidating Yang Wu, they wanted to scare Yang Wu away.

"Roar~!Roar~!"

How could Yang Wu be scared away by them, he was here to hunt, a creature like a hippopotamus that was so big and had no natural enemies should be very rich in qi and blood, in Yang Wu's eyes, these were the source of moving life!

"Ang~......"

The leader of this piece of hippopotamus was angered by Yang Wu, when did a single underage male lion become so arrogant?! If the whole lion group is here, it will be cowardly, and a juvenile male lion, it dares to take the initiative to attack.

The hippo leader rushed towards Yang Wu straightly, and the opening and closing of that mouth could swallow Yang Wu.

Even if Yang Wu didn't take it seriously, he was still ready for battle, and the lion fought the rabbit with all his strength, not to mention that he hadn't fought with the hippopotamus yet.

Yang Wu's footsteps stood still, and when the hippo leader rushed within two meters of Yang Wu, he moved.

This time he chose to be tough, in the past, in the face of large animals, Yang Wu was dodging and fighting, but today facing a hippopotamus of this size, he can just fight with all his strength!

"Iron Mountain!"

The buffer distance of two meters is enough! Tie Shan's movements and charging are completed.

"Bump!"

Yang Wu was hit by the force of the shock and took three steps back, but the hippo leader was knocked into the ground and sat on the ground and slid backwards for two meters.

The bones of the hippopotamus are still relatively thick, and Yang Wu Dacheng's Tieshan can break the bones of adult male lions, but it does not break the bones of the hippo leader.

Yang Wu just felt that his shoulders were a little sore, after all, the strength of the hippopotamus was still very large.
