There are such giants in the deep sea, they stand at the top of the marine life chain, in the 10,000-meter deep sea is a hegemonic existence, 71% of the earth is ocean, and the ocean area we can explore is less than 5%, and some new discoveries always appear from time to time, slowly revealing the miracles and horrors hidden in them. There are also many marine animals on Earth that are very scary for humans.

It feeds mainly on zooplankton, small fish and other jellyfish.
1. North Pacific giant octopus
The North Pacific giant octopus, also known as the North Pacific giant octopus, is a giant octopus. It lives in the sea close to the coast and belongs to the mollusk. Studies have shown that they can perform short- and long-term memories, have incredible ability to observe, learn and solve problems, can open cans, imitate other octopuses, and successfully pass labyrinths created by humans in experiments.
The giant octopus of the North Pacific is large, weighing about 15 kilograms and reaching an arm span of 4.3 meters. The head of the giant octopus is large, round, and usually reddish-brown. They can achieve the purpose of changing color through unique pigment cells, and can even be subtly mixed with intricate corals, plants, and rocks, and they can be found in various temperature waters of the Pacific Ocean, from Southern California to Alaska, from the western Aleutian Islands to Japan. Giant octopuses hunt at night, mainly shrimp, clams, lobsters and fish. They even attack and devour sharks, as well as birds. The giant North Pacific octopus relies heavily on its highly developed senses, with tentacles covering up to 280 suction cups, each containing thousands of chemoreceptors that give it a keen sense of touch and taste.
