Hello I read on wikipedia that an octopus has 8 arms rather than tentacles. Is this true?

This is largely a semantic matter, I believe. I’m not a cephalopod biologist, but I mostly see “arms” in them as those long, tapered limbs, with two rows of suckers along its entire length - this is what most octopuses have for all of their limbs, so calling them all arms would make sense.

Tentacles have always seemed to me to be more club-like. An un-suckered tapered part with a wide distal club with many suckers on it, or some variation on that general idea.
