The common octopus can hear sounds between 400 Hz and 1000 Hz, and hears best at 600 Hz. [61] 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]
Output of a computer model of underwater acoustic propagation in a simplified ocean environment. A seafloor map produced by multibeam sonar. Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries.
Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders. [9] Hearing is well-developed in carp, which have the Weberian organ, three specialized vertebral processes that transfer vibrations in the swim bladder to the inner ear.
The octopus is one of the most unexplainable animals on the planet, contested only by the platypus, the echidna, and the angler fish. And trust us, you don't know squat about what it can do.View ...
Some cephalopods accompany this expulsion of water with a gunshot-like popping noise, thought to function to frighten away potential predators. [ 73 ] Cephalopods employ a similar method of propulsion despite their increasing size (as they grow) changing the dynamics of the water in which they find themselves.

Scientists were expecting the octopus to work on problem-solving solutions by understanding how the screw top lid works and opening it with its arms. But the octopus bypassed the screw top completely.
This increased demand is met by an increase in the stroke volume of the octopus' heart. [20] The octopus does sometimes swim throughout the water, exposing itself completely. [15] In doing so, it uses a jet mechanism that involves creating a much higher pressure in its mantle cavity that allows it to propel itself through the water. [20]
