Similarities and Differences in Octopus vs Squid

Octopus says that Squids are fishfood for Suckers!

Squids say that Octopuses better run from in my Tentacles!

Well first of all the let talk grammar - there is an Octopus, in plural there are Octopodes (also acceptable is Octopuses or Octopi) there is a single Squid (also use Squid when refering to a collective group) and you say Squids (when there are two or more species of squid). There are 300 species of Octopi. There are 298 known species of Squids. Genetically both Octopuses and Squids are both from the Kingdom Animalia. Both Octopuses and Squids also share the same Phylum, Class, Subclass, orders, and Superorders evolutionarily. Both Octopuses and Squids live anywhere from the tropics to the temperate zones greographically. Both Octopuses and Squids live only in salt water. Both Octopuses and Squids have blue blood due to both having copper in their blood chemistry. Octopuses are cephalopods. Squids are head-footed cephalopods. Octopuses have eight arms that each have single or paired rows of suckers but not sucker rings, hooks or fins; and a mantle, and a head. Squids have eight arms and two tentacles that are paired that each have some hooks, suckers and sucker rings; and also have two fins; and a mantle, and a head. Octopuses use their arms to catch prey and move about floor of the ocean. Squids use all eight arms lined with suckers and two specialized tentacles. Octopuses use combinations of spinning and grasping with flexing to hunt. Squids can use their tentacles independently and can reach out to catch and hunt. Most octopuses do not have fins, rare deep water octopuses may be an exception. Squids have 2 fins on their head. Both octopuses and squids are related to snails and other molluscs. Unlike snails, Octopuses do not have shells or bones. Squids have a pen, it is stiff like a flexible backbone. Both Octopuses and Squids have hard, parrot-like beaks for killing, and tearing flesh from prey. Octopuses and squids can swim in any direction and can alter their course quickly by way of jet propulsion, or the sucking water into a muscular sac in the mantle cavity and quickly expelling out a narrow siphon. Octopuses generally move best in at high speeds, with movements like gliding to cover distance. Squids use fins located on their heads to steer and stabilize while propelling themselves at low speeds. Octopuses live in dens on the sea floor eating bottom-dwelling crustaceans. Squids live in the open ocean and eat fish and shrimp. Octopuses are always hunting. Squids in deepwaters may become scavengers. Octopuses are solitary living alone in dens. Squids may live in large schools, others are solitary. Octopuses have a definite mate and mating ritual which involves a female laying eggs in a den, and sealing off the den until she dies and the eggs are hatched. Squids often mate in groups, laying eggs on the ocean floor or in seaweed then leaving them to hatch on their own. Both Octopuses and Squids die after their reproductive cycle ends. Both generally will die near the young to be eaten by the new Octopus or Squid hatchlings. Octopuses can be from 1 cm-5 m in length when fully grown. Squids range from 1 cm - 20 m. The giant Pacific octopus has a life span of only four to five years, yet it can weigh 270 kg! The Giant Sea Squid may live longer, and have been seen to outweigh the largest octopus and can grow to double or more in size. Octopuses live from 6 months to five years. Squids live from 9 months to 5 years. Octopuses and squids can expel a dark cloud of ink from an ink sack, this ability is used to confuse natural predators, and is an escape mechanism. Octopuses use their high speed movement to evade predators. Squids have been known to travel at high speeds using their fins as wings to leap above the water, literally flying away from predators. Both Octopuses and Squid have the ability to change color and camoflage their bodies to match intricate reef and sea floor patterns. Octopuses and Squid are prey to common predators ; fishes, seals, whales, moray eels, sea stars and a few species of birds. Several Octopuses have the ability to inject poisons that cause paralysis. Some Squids may also have similar enzymes. Most Octopuses and Squids poisons are too weak to effect humans, with the exception of the Australian blue ringed octopus who's stronger poison will kill a human in minutes or less. Octopuses are not generally found in the deepest parts of the ocean. Squids are found in the deepest ocean, generally seeking protection in a large school...some squids also have Bioluminescence at this depth ( so far no Octopus has been found that produce light ). Octopuses and squids have excellent vision, but may be color blind. Octopuses and squids register smell from pits under their eyes. Octopuses are extremely sensitive to touch, but cannot discriminate between heavy and light objects. Sqiuds are less but similarly coordinated. Octopuses have taste receptors all over their bodies. Squids again have a less sensitive but similarly coodinated sense of taste. Human being eat both Octopuses and Squids. Octopuses are pickled, and called Octopothi. Squids on menus may be called Calamri, also black pasta is made with squid ink.Octopus fishers trawl using weighted chains that drag along the ocean floor, scaring the octopuses into a net. or by lowering traps which octopuses will use unwittingly for shelters - also sometimes by spear and drift fishing methods. Squids fishers catch them by jigging- the shining of bright lights and drop lines into water with special lures called jigs, which they jerk up and down, attracting squids with light and movement; other methods involve the use of large seine nets that encircle the squids, form pockets and trap them. And finally can it be true when You may have heard tales of Octopuses and Squids sinking ships.Very few Octopuses if any have been recorded having sunk ships. Greek narratives speak of a creature called a Kraken seized large boats and sank them. The animal they were describing may have been the giant squid, although it is unlikely that these stories are entirely true. Much later in history you would have giant squids in novels llike 20,000 leagues under the sea and in Moby Dick. Although the Octopuses and Squids get one final hurrah from science fiction and horror writer H.P. Lovecraft and an occult book known as the Necronomicon...an Octopus or Squid headed immortal Ancient One named Cthulhu is the primary overlord of the world and the first lord of darkness and interdemensional powers. Cthulhu is the grand dragon of Octopuses and Squids ancient ancestry, and is probably one of the scariest creatures ever created in the annals of all science fiction. Those who have not read 'The Call of Cthulhu' by H.P. Lovecraft should do so. All hail the Octopuses and Squids, brothers and sisters and the evolutionary descendents of Cthulhu. No matter how many arms or tentacles they are old as time, and I hope you know them a little better now.

No actual Octopus or Squid were harmed in the production of this Hub. We respect all species equally despite their unwillingness to be eaten by humans.

Chthulhu was asked to appear as a correspondent in support of the works of H.P. Lovecraft, we never asked him to work for us but you know the Ancient Ones. If you have seen him please don't bother calling.

So hubs can be humorous also, that is good, I recently lost my back teeth and have yet to find them and wish I had a parrot-like beak to tear the flesh from my prey.

Question: What is the significance of squid or octopi being thrown on to the ice at hockey games is that an ancient pagan ritual. Did pagans play hockey?

I would say octopus tastes better.

Somethgblue, I think the significance of octopus being thrown on ice at hockey games probably is symbolic of being like a squid out of water. Your time is up, or at least it would be for the poor octopi or squid. I think the Vikings might have had something like hockey, but there were no set rules. Just ice sticks, and the puck probably was the squid.

Keep on Hubbing. Blake4d
