Abnormal octopus with 9 arms in Japan
Octopus has 8 arms in case you don’t know… in fact the word Octopus is derived from Greek word which literally translate to ‘eight-legs’.
People often referred to the arms as tentacles, but it is not a biological correct term. Octopuses don’t have tenctacles, squids do.
