These octopuses have around 500 million neurons, around 350 million of which are along the arms, arranged in clusters called ganglia. The research was conducted on live Giant Pacific octopuses ( Enteroctopus dofleini) and East Pacific red octopuses ( Octopus rubescens), both native to the North Pacific Ocean. "There are a lot of open questions about how these nodes in the nervous system are connected to each other." "One of the big picture questions we have is just how a distributed nervous system would work, especially when it's trying to do something complicated, like move through fluid and find food on a complex ocean floor," said neuroscientist David Gire of the University of Washington.

And now scientists have determined that those neurons can make decisions without input from the brain.

But a faster octopus from New Zealand named Ozy opened a jar in just 54 seconds.

Scientists have observed them using an empty coconut shell as their mobile home.Īlso, an octopus named Billye from the Seattle Aquarium was able to open a jar pill bottle with a snack inside, which took it five minutes to twist and push the jar.
OCTOPUS TENTACLES HOW TO
In an environment where these intelligent cephalopods are restricted and do not provide them enough stimulation, they are known to engage in autophagy or the removal of specific organs that are unnecessary.Īnother bizarre fact about them is that they also know how to use tools. Shima Marineland flexed the tentacles of the octopus as it is the most recent discovery of a bizarre multiple-armed octopus.ĪLSO READ: How Does An Octopus Taste Using Their TentaclesĪccording to Ripleys, one bizarre behavior among the species of octopus in captivity is that they eat their arms when they are bored. Then in November 2020, a nine-armed octopus was also found by a fisherman in Japan. Toba Aquarium has exhibited six other mutant octopi that have between nine to 56 tentacles within that time.

Pink Tentacle reported that this remarkable creature was the same as the 96-armed octopus that bifurcated with its eight main tentacles creating branches to form other tentacles to the shock of many people from about half a century ago. Similarly, in 1957, an 85-tentacled Common Octopus (Octopus vulgaris) was also captured at nearby Toshijima Island. Scientists could not fully explain this phenomenon, but they believe that it could result from atypical regeneration that occurred after the octopus suffered an injury, a process known as bifurcation, which is quite common among the species of octopus. Shima Marineland Aquarium posted several photos on their Twitter account last November 23, 2020:

Some were asking for the authenticity of the photograph of the 96-tentacled octopus, in which authorities confirmed that it is a real octopus that is now on display at Shima Marineland in Japan.Īccording to Snopes, the octopus has eight regular tentacles but branch off into smaller tentacles, which is 96 arms all in all. All of its baby octopi hatched with eight tentacles but died a month later. The octopus died five months later, but it could lay eggs before that, making it the first multiple-tentacled octopus to do so in captivity. In a 2008 report by Pink Tentacle, there lived an octopus in Shima Marineland Aquarium, in the town of Shima, with 96 tentacles weighing 7 lbs (3.3 kg) and measuring about 3 ft (90 cm) long when it was captured near Matoya Bay in December 1998. Nature is indeed marvelous with all its wonders on land, sky, or deep in the ocean, just like the viral photo from of a 96-armed octopus captured several decades ago, shocking many people.
