The deadly Mara River, the suicide migration of millions of horned horses.

　This is a true human observation of a great migration of animals rare in natural history. The galloping of millions of horned horses created the Great Migration. They broke through the ambush of the lion and leopard, crossed the crocodile trap, and leapt over the cliff of death. Bones and blood flowed everywhere they passed. The martyrdom of millions of horned horses is the price of a baptism of life, a racial optimization, and the interpretation of an ironclad law of nature.

　　34-year-old John is a professor of zoology at the University of Oxford, England, has a unique preference and research on horned horses.In March 2018, he decided to travel to Kenya, East Africa, to follow the entire migration of horned horses and photograph them. His close friend, Professor Maya, also asked to go along.

　　In August 2018, John and Professor Maya traveled to Tanzania's Serengeti National Park, where the Serengeti savannah was well rained, grassy, and the vast grasslands were scattered with foraging horned horses.

　　"Why the migration?" Doubt hovered in Maya's head. John seemed to see through his thoughts: "Horned horses have superior growth ability, they have broader incisors than other herbivores and are able to sweep up grass faster than other herbivores. They are also extremely prolific, as in the case of long-distance herds of horned horses, a quarter of which are newborn babies, making them far more numerous than any other mammal in the savannah. If the lion is at the top of the food chain in the savannah and is the king of the beasts, then the horned horse is the most dominant animal in terms of numbers and has a direct impact on the prosperity of the savannah. According to statistics, in the Serengeti Savannah of Tanzania, there were only 190,000 horned horses in 1957, growing to 1.44 million in 1977 and 1.68 million in 1989. And the lion population was only 2,500."

　　Maya exclaimed, "Aren't there horned horses everywhere in East Africa, then?" John smiled, "Nature has its own magic, it arranges things."

　　Early one October morning, Maya suddenly felt the vibrations of the prairie, "Look, it seems they are on the move." Wambui called out, "We are going to follow them."

　　The herd of horned horses came overwhelmingly, as if there were only horned horses in that world, and the only horned horses between heaven and earth rolling and running.

　　John says that because there is no tender grass here, the horned horses must make a short run to the Mara River, and the only way to get there is to cross the big, fast-flowing river to reach the other side of the river, the fertile and rich Maasai Mara savannah. This is definitely not a tender journey, but rather an elegy for the survival of the weak, the horned horses must run to the Mara River in a short period of time and cross the fast flowing river to reach another fertile grassland for salvation.

　　After a week of tracking, John said to Maya, "The map shows a big canyon up ahead, which is the only way for the horned horses to migrate." After about 2 hours of driving, there was no road ahead and a cliff 10 meters wide and about 50 meters deep appeared.

　　"Is it possible for these horned horses to get through? I'm sure they'll change their course." Maya suspected.

　　A moment later, the army of horned horses came galloping in. The horned horses also seemed to smell the icy air coming from the canyon. But their speed didn't slow down at all, but ran faster and faster, like an arrow off the string. When they reached the mouth of the cliff, the lead horned horse jumped up and rushed towards the cliff. But how could this leap over a 10-meter wide cliff? After only a zone leap of 2 meters, he fell down the cliff.

　　And yet, such was the suicidal approach to a miracle of life!

　　The horned horses in the back stepped on their companions in front of them in the fall for a second bounce, although they still couldn't jump over this cliff, however the horned horses had been able to give their companions behind them several jumps after the first few waves, gaining time and space. Finally, using inertia, the army of horned horses made their way over the impossible cliff and reached the other side.

　　Jeeps don't go over cliffs, so John and the others returned to the road to figure out how the horned horses would migrate to the Mara River in Kenya, where they set up their cameras on the roof of the car and waited patiently.

　　After crossing the river, the horned horses will enter the "Garden of Eden" where the grass is abundant; if they don't cross, they will starve to death due to lack of grass and water. There are two animals in the Mara River that the horned horses will inevitably encounter during the crossing: the Nile crocodile, the largest and most ferocious in the world, and the hippo, known as the "African River King".

　　Between the sky and the earth, a vast expanse of horned horses were galloping towards the Mara River. Millions of horned horses' hooves were rumbling and the momentum was magnificent.

　　But strangely enough, the millions of horned horses in front of the horned horses rushed to the shore, came to a "sudden stop", and all stopped abruptly.

　　Half an hour passed, but the horned horses still didn't move. Suddenly, the mud around the horses moved, and a pair of ferocious and greedy eyes appeared, aiming at the horned horse. Suddenly, the mud splashed and a huge crocodile swooped out and bit the horned horse's neck.

　　The horned horse on the shore witnessed the Nile crocodile kill the magnificent horned horse, without any reaction, as if it was used to such scenes.

　　It was then that the danger in the Mara River became clear: more than a dozen Nile crocodiles buried in the mud leaped out and chased the horned horses down the river in two groups. Soon, more and more Nile crocodiles emerged from the water, crawled out of the grass and trees on the bank, and all went down into the river, forcing the horned horses that were moving forward.

　　In the face of death, the horned horses on the shore instead were not afraid. One of the horned horses jumped high into the river and was the first to swim across the river. A steady stream of horned horses jumped into the river and rushed over like a storm. The world's most spectacular river crossing of the horned horse began.

　　A large Nile crocodile was the first to guard the river area through which the horned horses had to pass. It opened its mouth wide, revealing two rows of long, saw-like teeth, and waited for the horned horses to enter its range of attack.

　　However, fear and death along with the horned horses were overwhelmed by the river. More and more horned horses converged into the Horned Horse Frenzy and fought forward to cover up the kill. The Nile crocodiles, fearful of their advancing foes, dived into the water to avoid the vortex formed by their lives. After numerous casualties, the horned horses finally broke through the Nile crocodile's defense line.

　　The horned horses gradually swam into the middle of the river. The water in this area was so fast that some of the horses were washed away due to exhaustion. But as long as they were alive, the horned horses were still making every effort to swim across to the other side of the river, which was the Mara River, the paradise of their hearts.

　　After a few months here, the horned horses will set out again to cross the Mara River and return to the Serengeti in Tanzania, 3,000 kilometers away. At that time, they will once again be challenged by hippos and Nile crocodiles. The horned horses win time and space for their fellows each time by their heroic death, thus ensuring the survival of the entire population. Perhaps running, migrating, dying and fighting is all they live and breathe."
