Octopus is one of many fish species, mainly distributed in tropical and subtropical regions, and distributed in many sea areas around the world. From the distribution range of this kind of fish, we can see that they belong to marine fish. However, there are more detailed classifications of marine fish, such as deep-sea fish or shallow-sea fish, which live at different depths and have different adaptability to seawater pressure.
Octopuses are marine fish, but they live in water depths ranging from 15 to 360 meters. Compared with freshwater fish and some marine fish, they already live in very deep water, but they still do not meet the requirements of deep-sea fish. Some deep-sea fish can even live thousands of meters under the sea, and their ability to withstand water pressure is much better than octopus. The depth of distribution of red fish in different chapters is not certain, and the depth of distribution of red fish in different times or seasons will also change.
? It has been introduced above that octopus belongs to marine fish and originally lives in the sea. Therefore, the breeding of octopus is more troublesome, compared with the breeding of freshwater fish, it will be much more troublesome. But there are farmed octopuses in some countries, such as Japan. In the market, there are some artificial breeding. However, unlike ordinary freshwater fish farming, octopus farming requires a special way, generally speaking, the special way of cage farming will be used to make octopus grow normally.
