Neither. It has 8 tentacles.

I originally thought that the correct term was "Tentacles" but in reality an octopus is said to have arms. Here is some info: http://en.wikipedia.org/wiki/Octopus Thanks Scienceoverignorance.

Tentacles... and they are deaf! (and FUGLY)

true i guess... thx all!

Could be 4 & 4... 4 arms, and 4 legs to go with them...lol

They have 8 testicles... I mean tentacles.

1) "The octopus (Greek ΧταπÏŒδι (Οκτάπους), 'eight-legs', with plural forms: octopuses, octopi, or octopodes, see below) is a cephalopod of the order Octopoda that inhabits many diverse regions of the ocean, especially coral reefs. The term may also refer to only those creatures in the genus Octopus. In the larger sense, there are around 300 recognized octopus species, which is over one-third of the total number of known cephalopod species." "Octopuses are characterized by their eight arms (not tentacles), usually bearing suction cups. These arms are a type of muscular hydrostat." Source and further information: http://en.wikipedia.org/wiki/Octopus 2) "Tentacles can refer to the elongated flexible organs that are present in some animals, especially invertebrates, and sometimes to the hairs of the leaves of some insectivorous plants. Usually, they are used for feeding, feeling and grasping. Anatomically, they work like other muscular hydrostats." "The phylum mollusca includes many species with muscular hydrostats in the form of tentacles and arms (octopuses do not have tentacles: they have arms). Tentacles are longer than arms and usually have suckers at their tips only. Squid and cuttlefish have eight arms like octopuses, and also two tentacles, which is one good way to distinguish squid from octopuses." Source and further information: http://en.wikipedia.org/wiki/Tentacle 3) "In anatomy, an arm is one of the upper limbs of an animal. The term arm can also be used for analogous structures, such as one of the paired upper limbs of a four-legged animal, or the arms of an octopus." Source and further information: http://en.wikipedia.org/wiki/Arm 4) As a conclusion, octopuses don't have tentacles. Octopuses have arms. However, the name "octopus" comes from the Greek á½€κτÏŽπους meaning "eight *legs*". So what we are calling arms today, was named legs by the old Greeks.

8 arms. They are commonly mistakenly called tentacles but they are considered arms. The two longer appendages of a squid are examples of tentacles.

8 arms silly, you don't need to walk underwater.

neither: six arms and two legs. See http://www.telegraph.co.uk/news/newstopics/howaboutthat/2547597/Octopuses-have-two-legs-and-six-arms.html
