Octopus is called the longest fish in the ocean, and it is normal to be about 10 meter long, but the longest octopus found can be about 15 meter to 18 meter long. This figure is scary, and the weight of octopus is amazing. Ordinary seafood is generally around 300 kilograms, and the largest octopus can grow to nearly 500 kilograms, which means that an octopus weighs nearly half a ton and may need dozens of people to lift it.

In fact, octopus is very rare in life, because this kind of fish actually lives in the deep sea and rarely appears on the sea surface or shallows, but once this kind of fish is found, it often indicates that something will happen. Because yellow croaker actually has another name, which is earthquake fish. Because someone once found traces of yellow croaker in the sea, it was very strange that this deep-sea fish suddenly appeared on the sea, and then an earthquake happened.

Therefore, as long as people find yellow croaker in shallow water, it indicates that natural disasters are happening. This fish has a red back. It looks like a dragon when swimming in the sea. So, for a time, it was said that dragons were seen in the sea, or sea monsters were actually octopus.

Yellow croaker is a fierce fish in the deep sea because of its length, width and height, and its teeth are as dense as Daiyu. If bitten, it will hurt. In the deep sea, octopus feeds on squid and small fish and shrimp. Because of its huge size, it can also be called the overlord in the deep sea. Compared with animals such as sharks, its size is not small. The key is that it is particularly long and can be entangled, which is also an attack feature.

Because most of them are active in the deep sea, people don't know much about them. The longest octopus found so far is about 18 meters, but whether there is any longer one is still a mystery.
