Uncover the secret of the crocodile lake

  The crocodile is one of the most ferocious carnivores on the planet, and the African Nile crocodile is chilling with its huge size and brutal attack. If there are 10,000 Nile crocodiles living in a lake, what kind of horror scene would it be?
  There is such a terrible place on earth, it is the famous lake of crocodile in Africa – Lake Turkana.
  Desert Gem
  of Africa Kenya can be described as a haven for wildlife, where the green grass everywhere, an oasis, home to thousands of animals. However, northern Kenya is a nightmare place.
  If you fly through the northern part of Kenya, you will feel the cruelty and injustice of the creator: the land under the feet is extremely dry, the desert is inaccessible, the sights are desolate, and almost no creatures live here. The plane kept flying forward. Suddenly, a striking blue-green color appeared in the wilderness, as if it were a sapphire set in the desert. As the distance gets closer and closer, the blue-green is getting bigger and bigger, and finally, a beautiful lake appears in front of you.
  This blue-green lake is the famous inland lake in Africa, Lake Turkana. It is not only the largest lake in Kenya but also one of the largest saltwater lakes in the world.
  Although surrounded by deserts, Lake Turkana is amazingly beautiful. This area of ​​6,405 square kilometers is rich in cyanobacteria. The cyanobacteria float in the water, making the entire lake surface a pleasant blue-green. Standing by the lake, the breeze is swaying, and the lake is rippling, making people feel like they are in a dream. There are also three small volcanic islands in the lake, which are like pearls dotted in the blue waves and look beautiful.
  However, the seemingly beautiful Lake Turkana wanders with a terrible demon, and the lake is also lying on the shore of the sun-baked behemoth – African Nile crocodile.
  Birth is
  the Nile crocodile is the largest crocodile on earth, they body up to 1.56 meters can weigh over one ton. The fierce and brutal Nile crocodile can not only attack large herbivores such as wildebeests and buffaloes, but also often attack humans.
  Every day, when the sun rises, the shores of Lake Turkana are full of Nile crocodiles enjoying “sunbathing”. They open their mouths and look chilly. They can be seen from time to time on the lake. The figure that swims to the Nile crocodile. The number of Nile crocodiles in Lake Turkana is very large, they occupy the entire lake, and the number has reached horrific 10,000.
  You may ask: Where did so many Nile crocodiles come from?
  As the name suggests, the Nile crocodile lives in the Nile and its tributaries, while Lake Turkana is an independent lake surrounded by a desert. The Nile crocodile wants to cross the desert to reach it. It is estimated that it will be less than halfway through. The high temperature in the desert is baked into crocodiles.
  To unlock the mystery of the Nile crocodile in the lake, you must first understand the origins of Lake Turkana. Turning over the “family tree” of Lake Turkana, the experts were surprised to find that the origin of this lake is not simple: it was formed tens of millions of years ago, and the distant ancestors of humanity lived by the lake. They played here. Fishing, hunting, and starting from here, slowly moving towards the world. Therefore, Lake Turkana has also won the “human cradle” reputation.
  Through scientific investigations, experts found that at the earliest time, Lake Turkana was connected with the Nile River, that is, Lake Turkana was the upper reaches of the Nile. In order to seek a better life, the Nile crocodile went down the river and came to live in this lake. Later, the climate changed. With the onset of severe drought, the passage between Lake Turkana and the Nile was slowly interrupted, and a large desert was replaced. Therefore, the Nile crocodiles have never returned to the Nile, and they have to settle down in the lake for generations.
  Lake Life
  Nile crocodile great size, their appetite is also very alarming, an adult Nile crocodile meal can eat dozens of kilograms of meat, they are extremely acidic gastric juice, animal bones and skins will be digested thousand Second net. Although they can no longer eat for a year after a meal, but 10,000 crocodiles have to survive, they must have a large supply of meat.
  Where did the food of these crocodiles come from?
  Let’s take a look at the surroundings of Lake Turkana. The environment around the lake is very harsh. It is full of deserts and wasteland. During the day, under the scorching sun, the temperature in the desert can reach 50 ° C, the ground temperature is higher, enough to roast eggs. Although the temperature around the lake is high, the rainfall is pitiful. The annual rainfall is less than 200 mm. Often the rain has not yet reached the ground, and it is evaporated by high temperature heat waves. Due to the extreme drought, there are only a few super drought-tolerant plants rooted around Lake Turkana. They grow sparsely on the scorching sand, and the animals are completely traced – no animals are willing to venture here.
  Obviously, there is no food on the land around the lake for the crocodiles to enjoy. The only thing they can count on is the blue-green lake that makes them settle down.
  People fought over crocodile
  despite extremely desolate around Lake Turkana, the lake is an entirely different story: here is rich in perch, tiger fish, fin fish and more fish, especially perch can grow to two meters, The weight can reach hundreds of kilograms. It is their existence that provides a rich source of food for the Nile crocodile. Every day, in addition to the sun, the Nile crocodile swims around the lake, hungry, and can’t spend much effort to catch a delicious fish.
  So, what do these fishes of Lake Turkana grow up to eat? The secret is on the cyanobacteria. Because the lake is rich in minerals, it is very suitable for the growth of cyanobacteria. Therefore, the cyanobacteria are covered here by the whole lake. This provides a rich source of food for small fish and some aquatic organisms. The big fish feed on small fish and form A complete biological chain.
  The Nile crocodile relies on the fish in the lake to survive, and the people living by the lake have to live on the fish. The indigenous people living here are called El Moro, meaning “people who eat fish.” Because the surrounding land barely grows any crops, the El Moro people almost all make a living by fishing. They often paddle a canoe, or use a spear to fish in the lake. People want to catch fish, and Nile crocodile is also doing their part; in many cases, there will be fierce conflicts between human crocodiles. Every year, there are scenes of crocodile wars. The crocodiles are rushed to the other side of the lake, and the death of the El Moro people by the Nile crocodile has also occurred.
  However, the most serious is not the conflict between human crocodiles. Due to the global warming, the water level of Lake Turkana is decreasing at a rate of 30 cm per year, which makes the lake’s alkali and salt content higher and higher. Scientists pointed out that if the water level of the lake continues to decline, it will affect the survival of the Nile crocodile and the El Moro, and the scene of the crocodile lake may disappear.
