According to the Kogokushima Aquarium, a fisherman donated the octopus after catching it in the waters off the city’s Shikamachi district in early June, and the gender of this octopus is still unknown.
It is usual that the octopus animal belongs to the group of mollusks, and the order of cephalopods. It has a prominent head, and a mouth surrounded by 8 arms with simple suckers.
The octopus is soft and has no skeleton. This enables it to squeeze its body and hide in narrow crevices, as the only solid part that the octopus has is the beak-like jaw in its mouth.
Normally, the original eight arms of an octopus have suction “cups”, but they can branch off to other limbs after being chopped up by fish and other predators that attack them. At this point, the octopus’ arms can regenerate and, in unusual cases, develop into multiple limbs.
recurring phenomenon
Back in the Kogokushima park octopus with 36 arms, it is still unknown whether the presence of these arms instead of 8 was caused by a sudden mutation or a congenital cause.
In December 1998, a 96-armed octopus was found in Shima, Japan. It weighed 3.3 kg (about 7 lbs) and was 90 cm (3 ft) long when it was captured in Matoya Bay.
After 5 months, (before his death), the octopus laid eggs, which made it the first octopus with extra arms to lay its eggs while in captivity, but the octopus young did not survive and died after a month.
Before this octopus, the most famous octopus was an 85-armed octopus, captured in 1957 on nearby Toshijima Island, also in Japan.
Like the Marineland Chimaa octopus, this remarkable creature had 8 main arms that branched out to form dozens of limbs, and it caused quite a stir when it was first introduced to the Toba Aquarium half a century ago.
A few years later, the specimen was loaned to the National Museum of Nature and Science in Tokyo, where it gained the attention of Emperor Shōwa.
