The answer is true, first of all, this animal is real, but not as the animals in the trees, It is a common octopus and it's been up to. Octopus usually live in rocks, coral, or burrows and because they are invertebrates, The trigger CO2 breathing high CO2 level will decrease pH (making more acidic), which cause the problems quickly. Exhale is the main drive for breathing. If the octopus is the king of camouflage, then the brown octopus is the king of kings, the brown octopus changes its colors to match those of the model species and contorts its arms to match particular shapes and forms, that the octopus may even decide what particular animal to mimic depending on the predator. When confronted by a predatory damselfish, for instance, the octopus takes on the guise of that fish's common enemy.
