The most alien-like creature in the world is octopus.

Octopus is recognized as one of the most intelligent animals in the ocean and a rare intelligent creature on the earth, and it looks like an alien. It has skills that we humans are eager for, such as deformation and camouflage, extreme escape, spraying poison, regeneration and so on. It has three hearts, nine brains, 5 million neurons and more than 3, genes, which is three times that of human beings. It can also edit RNA.

Octopus's superb life skills are not possessed by any other creature on the earth. Octopus can use its flexible wrist to crawl between rocks, crevices and seabed, sometimes disguising itself as a bunch of corals, and sometimes as a pile of shiny gravel. Octopus can change its color and structure and become like a stone covered with algae waiting for its prey.

Octopus's life habit

It is carnivorous, feeding on cladocera and crustaceans (shrimp, crab, etc.), and some species eat plankton. This is not a question of whether it likes it or not, because stable structural myoglobin is a necessary condition for octopus to survive in the deep sea. It fights with lobster to compete for astaxanthin resources. Astaxanthin is the strongest antioxidant and a necessary condition to ensure the structural stability of myoglobin without oxidation.

Octopus sucks water into the mantle, and after breathing, it excretes water through a short funnel-shaped body tube. Most octopuses crawl along the bottom of the sea with suction cups, but when they are frightened, they will spray water from the body tube, and the jet water is strong, thus moving quickly in the opposite direction. When in danger, ink-like substances will be ejected as a smoke screen. Some kinds of substances can paralyze the attacker's sensory organs.
