There are more than 1.5 million biological species in the world, and it is said that only one-tenth of them have been discovered by humans, and many more will be discovered. Such a large base has led to the diversity of organisms, some creatures are so magical that scientists can't solve the mystery of their bodies for the time being, so today I will follow the watermelon video creator "Flathead Zoo" to see these magical creatures.
Electric eels are mainly distributed in the Amazon basin of South America, mostly in shallow ponds or on the shores of relatively turbid water bodies. Their body length can reach about 2.5 meters, and due to their unique discharge ability, they are one of the most terrifying freshwater creatures in the world.
Electric eels have a special type of discharge cell in their bodies. When the nerve signals of electric eels are stimulated, the cell membrane of such cells rapidly absorbs sodium ions and releases potassium ions. In this way, a certain voltage difference is formed at both ends of the cell, and the body is such a cell from beginning to end, just like a battery connected in series can generate a powerful voltage. The electrical energy released by electric eels can reach a voltage of three hundred to eight hundred volts. The super strong voltage set caused a strong bull to die instantly.
Scientists began working on new batteries, taking into account the discharge of electric eels: using printing technology to string together gels containing different ions. Just like several power-generating cells in the body of an electric eel connected in series, a powerful voltage is generated. Perhaps in the near future, our batteries will become extremely thin and light, and they can be carried around.
The lighthouse jellyfish is a small jellyfish, and the adult lighthouse jellyfish is only four to five millimeters in diameter. How does such a small creature achieve immortality?
In general, jellyfish have two forms throughout the life process: the first is the hydra type, which is fixed to the seabed or other substrate and extends the tentacles upwards for predation or defense; the other is the jellyfish type, which is suspended in the water and also relies on the tentacles for hunting. Half of the jellyfish began to lose their reproductive mission and then dissipated into the world.
But the lighthouse jellyfish is completely different from it, after breeding the deterioration of the physique led to poor living conditions, the lighthouse jellyfish began to "re-build" and began to return to the juvenile state! This is what is commonly referred to as rejuvenation. The scientific name for rejuvenation is called transdifferentiation — which refers to the transformation of one differentiated cell into another. Since the cells in the lighthouse jellyfish can undergo infinite transdifferentiation, the lighthouse jellyfish becomes a creature that can live forever.
However, due to the poor aggression and defense ability of the lighthouse jellyfish, it is often the food of various aquatic creatures, almost at the lowest end of the food chain, slightly humble.
After hundreds of millions of years of evolution, too many organisms have evolved amazing abilities that make people "marvel", and if scientists can understand and skillfully use them, I believe that the world will be an unimaginable appearance in the future.
