Trust us, seeing this act can send chills down your spine. Not having bones is the most significant advantage when you want to try such stunts. But that can involve directly attaching electrodes to exposed nerves, an invasive procedure that could harm delicate cephalopods. The squid can hear an wider range of sound from 400Hz to 1500Hz, they report in Comparative Biochemistry and Physiology, Part A.
One species deviates so wildly that it can take on the form of other marine animals. But the fact they can hear raises the possibility that these intelligent animals may use sound to catch prey, communicate with one another or listen out for predators. Science & Environment Yes, octopuses may not be able to appreciate the nuance of a Beethoven symphony, but maybe, just maybe, they can detect sound vibrations in the water in some capacity.This is why Octolab decided to conduct a series of experiments to determine whether or not octopuses can hear.In this particular video, a series of sounds in specific frequencies were played through speakers placed against the wall of one of the observation tanks.The frequencies used were 30, 50, 80, 100, 150, 200, 300, 350, 400, 500, 700, 750, and 1,000 hertz.In the video, you will notice that the nature of the experiment is purely observational.
Surely, they’re not completely deaf.
The scientist found a highly engaged and interactive communication between many octopuses.

Science & Environment How many hearts does an octopus have? He says the different abilities of the octopus and squid also reflect the environment they live in. Compared to fish, octopus and squid do not appear to hear particularly well.
They live with their eggs for up to seven months without eating, ensuring that streams of oxygen- and nutrient-rich water waft over them. 31 Jul 07 | An octopus has blue blood and three hearts. The scientists observed one particular repeated movement, that is, stand tall and extending their arms outwards. A larger heart that circulates blood to the rest of the body.The blood of the giant Pacific octopus has a copper-rich protein called hemocyanin that improves its ability to transport oxygen in cold ocean environments.They’re able to change their color and texture to camouflage themselves in the blink of an eye, thanks to a complex system of specialized pigment sacs called chromatophores, nerves and muscles.Octopuses have glands that produce a toxic ink which is then stored in large sacs.
Find out about these and other octopus facts. Matt Walker Top Answer. So Yan invented a non-invasive method, which involves placing electrodes on an animal's body to measure the electrical activity in its brain. You might only think of color changing technique when you hear about an octopus, but they also need to be social so that they can communicate to other octopuses. In this way, he could measure within just a couple of hours whether the brain of an octopus or squid responds to sound. 1 2 3.
When the animal is alarmed, it squirts the ink in a powerful jet in one direction that simultaneously propels the animal in the opposite direction, effectively clouding the water to confuse a potential threat while fleeing to safety.Adult female giant Pacific octopuses have about 280 suckers in each of their eight arms. Perhaps it can feel the sound vibrations from the tank glass and is curious?There definitely seems to be some reaction to each frequency.
Tactile, gustatory (that’s “taste” for us common folk,) and visual senses all play their role in providing octopuses with vital input from their environment.While it’s true that octopuses do not have any organs or specific body adaptations required to specifically discern sound, the question of octopus “hearing” has been posed before by marine biologists.Before you ask, “how can a creature hear without ears?” You should be aware that there are non-traditional ways to “hear.” In our human world, you can look at instances in which deaf people can detect sound by placing their hand on a vibrating speaker. Some years ago, it was found that octopuses usually killed each other and that time, scientists believed that octopuses may not be socially much active. The giant Pacific octopus has three hearts, nine brains and blue blood, making reality stranger than fiction. 16 Dec 08 | This is an excellent opportunity for you to become directly involved in exploring an area of octopus life that is as of yet under-explored.Word to the wise, when watching the video, it’s okay to lower or mute the volume. 0. Well, everyone is wrong. The discovery could open up a new understanding of cephalopod behaviour. Mothers usually die after their broods hatch.SOURCES: New England Aquarium, Oceana, The Natural History Museum, Monterey Bay AquariumThis story has been corrected to say that an octopus has arms, not tentacles.Connect with the definitive source for global and local news The exceptions are functions that require an Internet connection, e.g. West Midlands
However, sensory physiologist Hong Young Yan of the Taiwan National Academy of Science in Taipei, Taiwan suspected that octopus and squid might use another organ called the statocyst to register sound.The statocyst is a sac-like structure containing a mineralised mass and sensitive hairs.
