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
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

- Do octopuses' arms have a mind of their own?on November 2, 2020 at 5:45 pm
Often described as aliens, octopuses are one of most unusual creatures on the planet, with three hearts, eight limbs and a keen intelligence. They can open jars, solve puzzles and even escape from their tanks, aided by their eight ultra-flexible and versatile arms. But determining how exactly octopuses control all eight limbs is a puzzle that scientists are still trying to crack.
- Touch and taste? It's all in the tentacles:...on October 29, 2020 at 4:00 pm
Octopuses have captured the human imagination for centuries, inspiring sagas of sea monsters from Scandinavian kraken legends to TV's "Voyage to the Bottom of the Sea" and, most recently, Netflix's less-threatening "My Octopus Teacher." With their eight suction-cup covered tentacles, their very appearance is unique, and their ability to use those appendages to touch and taste while foraging further sets them apart.
- Death of sea life off Russia peninsula 'caused by...on October 23, 2020 at 3:41 pm
Blooming algae was behind a recent mass death of sea animals that saw octopuses and seals wash up on the shore off a Russian peninsula, scientists said on Friday in the final conclusion to their probe.
- Kamchatka marine life death caused by algae:...on October 12, 2020 at 5:07 pm
The mass death of sea creatures in Russia's Kamchatka region was caused by toxins from microalgae rather than man-made pollution, a senior Russian scientist said on Monday, citing preliminary findings of an investigation.
- Russian sea pollution forms massive moving slickon October 8, 2020 at 6:30 pm
Suspected toxic waste pollution off Russia's Kamchatka peninsula that caused the mass deaths of marine animals has formed a moving slick stretching 40 kilometres (25 miles) along the Pacific coastline, researchers said Thursday.
