how many tentacles does an octopus have

An octopus has zero tentacles. Instead, it has eight limbs called arms. These arms are covered with suckers along their entire length, unlike tentacles, which have suckers only at the tips. The distinction is important: octopuses possess eight arms, not tentacles. Their cousins, like squid and cuttlefish, have eight arms plus two tentacles. The arms of an octopus serve multiple purposes such as locomotion, feeding, sensing the environment, and manipulating objects
