Let’s take a look at this real-life tutorial on the creative origami method of the Japanese Kamiya octopus. The octopus is a marine animal. Although it has fish in its name, it is not actually a fish. Octopus belongs to the phylum Cephalopoda, order Octopus, and is the general name for animals of the genus Octopoda in the family Octopus. Because there are eight arms on the head, and the wrists are connected by membranes of different lengths, and there are 2 rows of stemless suckers on the wrists, so it is called the "eight-armed species". It is a marine animal, not a fish.
