First, it may be related to the octopus's own regenerative ability.
Nine-legged octopus appeared along the coast of Japan. Is this mutation or evolution? According to the witnesses in the coastal village of Miyagi Prefecture, Japan, this is the first time to see this situation. Even local researchers say that this situation is the first time in many years, and it is not difficult to understand that one of the three possibilities given may be related to the regeneration ability of octopus. After all, most marine organisms, especially those in the deep sea, will heal and regenerate from wounds because of their own functions after their limbs are eaten by other fish or organisms, just like the reason why gecko tails regenerate.
Second, it may be related to the chemical pollution of octopus.
The second point may be related to the chemical pollution of octopus, which is the most seriously polluted area in Japan. After all, Japan has developed a lot of chemical industries, and it has been reported before that Japan intends to discharge trillions of tons of chemical pollutants into the Pacific Ocean. It can be seen that this amazing amount must not be the first time that Japan has done such a thing, and the lesions caused by chemical pollution, chemical pollution and nuclear pollution are not only human beings, but even animals, so this nine-legged octopus is likely to be chemically polluted.
Third, it may be genetic variation.
The third possibility is related to genetic variation. After all, so far, these rare phenomena have impacted people's cognition and vision again and again. The mutated white bear, albino snake and two-headed turtle are all caused by genetic variation, and there are many wonders in nature. The known field is actually very small in the world, so this nine-legged octopus may be a genetic variation. Of course, why are we still investigating? We can only make the closest guess.
To sum up, welcome to discuss and pay attention!
