All octopus' have eight arms.
This is because of the Ancient Greek number eight (octo), which also has roots in the word OCTOGON (an eight sided shape).

Yes indeed they do!! Many, many species. A favorite in my area is the Giant Pacific Octopus.
The largest well-documented octopus known was a specimen of Enteroctopus dofleini (the North Pacific giant octopus). Somewhat questionable records exist claiming that this species can have arm lengths of about 30 feet.That would be about one car per arm, so 8.
There are many giant octopuses left in the world. Even though they are not on the endangered or threatened species, doesn't make them resistant to pollution. They are very sensitive to polluted waters. To answer your question Giant Pacific Octopuses are not endangered.
The size of octopus range between few centimeters to many feets. Californian Lilliput octopus range between 1-2 cm whereas the giant pacific octopus are as large as 14 feet and above.
They are born with 8 arms.
it's the same thing as an adult octopus so eight arms
8
The whole species of octopus is not entirely endangered, but there are some subspecies that are endangered, threatened, or close to being endangered: The Giant Octopus, a giant but gentle octopus, is listed as "Endangered" on the ICUN Redlist. The Pacific Northwestern Tree Octopus is not currently listed as endangered, but some people think that they should be because of their small numbers. There are probably many other endangered subspecies, but they are probably not as well known.
