Giant Pacific octopuses are able to recognise individual humans [66] and common octopuses can recognise other octopus individuals for at least one day. [ 67 ] In a study on social learning, common octopuses (observers) were allowed to watch other octopuses (demonstrators) select one of two objects that differed only in colour.
While octopuses generally avoid humans, attacks have occasionally been verified. For example, a 240-centimeter (8-foot) Pacific octopus, said to be nearly perfectly camouflaged, approached a diver and attempted to wrap itself around the diver and his camera. Another diver recorded the encounter on video.
Octopuses swim headfirst, with arms trailing behind. While most cephalopods can move by jet propulsion, this is a very energy-consuming way to travel compared to the tail propulsion used by fish. [67] The efficiency of a propeller-driven waterjet (i.e. Froude efficiency) is greater than a rocket. [68]

Octopuses have an excellent somatosensory system. Their suction cups are equipped with chemoreceptors so they can taste what they touch. Octopus arms move easily because the sensors recognise octopus skin and prevent self-attachment. [62] Octopuses appear to have poor proprioceptive sense and must observe the arms visually to keep track of ...
Octopuses are known to be shy and usually friendly towards humans, they usually just want to be left alone. Their strong suckers on their arms can be dangerous if they lock onto a human since the ...
Believe it or not, octopuses could be the ones to dominate Earth after humans. Scientists have recently made a riveting claim that these eight-limbed, marine invertebrates could become the ...
The octopuses use coconut shells discarded by humans which have eventually settled in the ocean. They probe their arms down to loosen the mud, then rotate the shells out. After turning the shells so the open side faces upwards, the octopuses blow jets of mud out of the bowl before extending their arms around the shell—or if they have two ...
