So, what do we call the eight limbs of octopus? Arms, tentacles? Studies suggest that octopuses have two legs and six arms. What is this classification based on? The eight tentacles of an octopus are divided into six arms and two legs. The legs function in movement while the arms help in the feeding process. Like other cephalopods, octopuses have camera-like eyes, [48] and can distinguish the polarisation of light. Colour vision appears to vary from species to species, for example being present in O. aegina but absent in O. vulgaris. [57] Opsins in the skin respond to different wavelengths of light and help the animals choose a coloration that camouflages them; the chromatophores in the skin can respond to light independently of the eyes.

No matter what, when octopuses mate, they die soon after. During reproduction, a male delivers sperm by inserting a specialized arm (usually the third right arm) into the female's mantle cavity, according to the World Animal Foundation. Sometimes he literally hands her the sperm, however, according to the Smithsonian article. Octopus uses Halibut to communicate. This is based on TCP, not HTTP, it is not possible to add HTTP headers to this communication channel.Attached to the brain are two organs called statocysts (sac-like structures containing a mineralised mass and sensitive hairs), that allow the octopus to sense the orientation of its body. They provide information on the position of the body relative to gravity and can detect angular acceleration. An autonomic response keeps the octopus's eyes oriented so that the pupil is always horizontal. [26] Octopuses may also use the statocyst to hear sound. The common octopus can hear sounds between 400Hz and 1000Hz, and hears best at 600Hz. [61] Why do octopuses need so many arms? Aren’t they supposed to be extremely intelligent? If humans can make it with two, isn’t eight a bit too much? Whether immortalised as giant monsters, fetishised in tentacle pornography or celebrated as psychic football pundits, octopuses have long fascinated humans. Octopuses tend to be solitary, though they do interact with other octopuses at times. Some species of octopuses hunt at night, while others only hunt at dusk and dawn.

Octopuses can create distracting patterns with waves of dark coloration across the body, a display known as the "passing cloud". Muscles in the skin change the texture of the mantle to achieve greater camouflage. In some species, the mantle can take on the spiky appearance of algae; in others, skin anatomy is limited to relatively uniform shades of one colour with limited skin texture. Octopuses that are diurnal and live in shallow water have evolved more complex skin than their nocturnal and deep-sea counterparts. [107] The octopus is classified as a cephalopod, along with other animals like squid and cuttlefish. Cephalopod refers to animals who have limbs attached to their head. In this sense, the octopus is said to have eight tentacles. The eight limbs are commonly referred to as tentacles. Although now there are arguments on the fact whether all the limbs should be called tentacles or not. Thomas, David (12 August 2008). "Octopuses have two legs and six arms". The Telegraph . Retrieved 30 July 2018. To most of us it has always seemed obvious that an octopus has eight arms. Octopuses have two legs and six arms Claire Little, a marine expert from the Weymouth Sea Life Centre in Dorset, said: 'We've found that octopuses effectively have six arms and two legs.'

Octopuses can also change color to hide and match their surroundings. They can turn blue, gray, pink, brown or green. The mimic octopus can also flex its body to resemble more dangerous animals, such as eels and lionfish, according to the World Animal Foundation.
