		The visceral mass, located in the anterodistal region of the octopus, is covered by the mantle, a muscular organ that consists of a cuticle underneath the epidermis.
		The nervous system of an octopus is highly developed, and the animal has a brain that is partially enclosed in a cartilaginous cranium; however it is not protected by the mantle cavity, but found within the head.
		This cryptic behavior of the octopus is possible because it possesses chromatophores, reflecting cells, and photophores, all of which are used to assist in the rapid change in appearance that make it difficult to spot the animal in its natural habitat.

		OCTOPUS, are carnivorous marine mollusk of the genus Octopus, order Octopoda, class Cephalopoda, phylum Mollusca, found worldwide in tropical and warm temperate waters.
		Much of their life is spent in hiding, and many species-such as the common octopus, O. vulgaris, which can grow to about 1 m (about 3 ft) long-choose a natural hole among rocks or in a pile of rubble.
		A small species, however, such as the pygmy octopus, O. joubini, which is about 2 cm (about 5 in) long, may prefer an empty clamshell having both valves still connected by a ligament; settling into one half, it pulls the shell shut with its suckers.
