octopus : any of a genus (Octopus) of cephalopod mollusks that have eight muscular arms equipped with two rows of suckers; broadly : any octopod excepting the paper nautilus — Webster   See also   OneLook


Roget’s II (Thesaurus.com), Merriam-Webster Thesaurus, Visuwords


Octopus is a soft-bodied, eight-armed mollusc of the order Octopoda. Around 300 species are recognized and the order is grouped within the class Cephalopoda with squids, cuttlefish and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the centre point of the arms (which are sometimes mistakenly called “tentacles”). The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight arms behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviorally diverse of all invertebrates. — Wikipedia

Teuthology is the study of cephalopods such as octopus, squid, and cuttlefish. It is a branch of malacology, the study of molluscs, in marine zoology. — Wikipedia

    Squids and octopuses are masters of camouflage, blending into their environment to evade predators or surprise prey. Some aspects of how these cephalopods become reversibly transparent are still "unclear," largely because researchers can't culture cephalopod skin cells in the lab. Today, however, researchers report that they have replicated the tunable transparency of some squid skin cells in mammalian cells, which can be cultured. The work could not only shed light on basic squid biology, but […]

    Octopus is a popular ingredient in many cuisines, with some 420,000 metric tons of this mollusc being caught worldwide each year. The rising global popularity of octopus has been attributed to the increasingly adventurous tastes of younger consumers, its nutritional benefits and the decline of traditional fish stocks such as cod. This helps explain why the food processing corporation, Nueva Pescanova, aims to build the world's first indoor octopus farm in Gran Canaria: a thousand-tank facility […]
