With many satellite or mini-brains, cephalopods are able to process certain information from its arm without consulting the main (central) brain. Like if you were watching TV, your hand could search for the remote or grab the popcorn without you even having to think about it! Common Octopus By: Dr. Chelsea Bennice What’s the difference between an octopus arm and a tentacle? In classical Greece, Aristotle (384–322 BC) commented on the colour-changing abilities of the octopus, both for camouflage and for signalling, in his Historia animalium: "The octopus... seeks its prey by so changing its colour as to render it like the colour of the stones adjacent to it; it does so also when alarmed." [165] Aristotle noted that the octopus had a hectocotyl arm and suggested it might be used in sexual reproduction. This claim was widely disbelieved until the 19th century. It was described in 1829 by the French zoologist Georges Cuvier, who supposed it to be a parasitic worm, naming it as a new species, Hectocotylus octopodis. [166] [167] Other zoologists thought it a spermatophore; the German zoologist Heinrich Müller believed it was "designed" to detach during copulation. In 1856 the Danish zoologist Japetus Steenstrup demonstrated that it is used to transfer sperm, and only rarely detaches. [168] Flexible biomimetic 'Octopus' robotics arm.

Indeed with their big eyes, curious nature and famously moody characters – one recent study found they deliberately throw rubbish at other octopuses – the creatures can seem strangely human.

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.

The Anatomy of Octopus Arms

An octopus has three hearts. One pumps blood through its organs; the two others pump blood through its gills, according to the World Animal Foundation. Octopus blood is blue because it has a copper-based protein called hemocyanin. Octopuses have short life spans. Some species only live for around six months. Other species, like the North Pacific giant octopus can live as long as five years. Typically, the larger the octopus, the longer it lives, according to the World Animal Foundation. Octopus is eaten in many cultures, such as those on the Mediterranean and Asian coasts. [160] The arms and other body parts are prepared in ways that vary by species and geography. Live octopuses or their wriggling pieces are consumed as ikizukuri in Japanese cuisine and san-nakji in Korean cuisine. [161] [162] If not prepared properly, however, the severed arms can still choke the diner with their suction cups, causing at least one death in 2010. [163] Animal welfare groups have objected to the live consumption of octopuses on the basis that they can experience pain. [164] In science and technology

Blanch the octopus: After thawing in the fridge for a day or so, bring a large pot of water to a rolling boil. Do not salt. Once the water is boiling hard, place the octopus in the pot, cover, and return to a boil. The cooking time will vary depending on the size: For small ones that can fit in your hand, cook for a minute or two. For medium (about a foot long and weighing less than a half-pound) boil for 4 to 5 minutes. For large octopus (around 5 pounds), boil for a good 8 to 10 minutes. I am posting Octopus Carpaccio today, even if carpaccio is not a traditional Japanese dish. Carpaccio is a dish of thinly sliced raw meat or fish, but I used boiled octopus tentacles. What makes it slightly authentic is that I used yuzu juice to make a vinaigrette and julienned perilla leaves as a topping. a b c d "Finned Deep-sea Octopuses, Grimpoteuthis spp". MarineBio. 18 May 2017 . Retrieved 14 May 2021. Octopuses bring captured prey to the den, where they can eat it safely. Sometimes the octopus catches more prey than it can eat, and the den is often surrounded by a midden of dead and uneaten food items. Other creatures, such as fish, crabs, molluscs and echinoderms, often share the den with the octopus, either because they have arrived as scavengers, or because they have survived capture. [86] On rare occasions, octopuses hunt cooperatively with other species, with fish as their partners. They regulate the species composition of the hunting group — and the behavior of their partners — by punching them.

They belong to the group of cephalopods, which includes four members including squid and cuttlefish.
