Scientists have recently found a breeding ground inhabited by 60 million fish in the depths of the Antarctic ice-covered Weddell Sea, each nest is evenly distributed on the seabed, and even fish are guarded, like a deep-sea giant city, a unique and unknown ecosystem, scientists are even more amazed, he has never seen such a spectacular scene.
According to CNN, the German polar research vessel Polarstern was surveying the seabed in the Weddell Sea last February when it accidentally discovered the breeding grounds of the Neopagetopsis ionah (scientific name: Neopagetopsis ionah). Antarctic neo-icefish are very special icefish, with transparent skulls and blood, is currently known to be a vertebrate without red blood cells, in order to survive in the low temperature, so the blood evolved antifreeze protein, to fight the cold.
Autun Purser, a researcher who has been practicing for 15 years, mentioned that "I have never seen such a thing, in 4 hours, we saw one fish nest after another, covering about 6 kilometers under the sea", the entire territory is equal to the size of the island country "Malta", and the breeding area is more than 240 square kilometers, on average, there is a fish nest per 3 square meters, it is estimated that there should be 60 million, and each nest is about 15 centimeters deep, 75 centimeters in diameter, some have fish eggs, but some have not been used. Each is about the same size and is surrounded by a circle of stones.
