![]() The smallest octopus is the Californian octopus, which only grows about an inch long. The largest octopus is the giant pacific octopus, which can weigh up to 600 pounds and have an arm span of up to 30 feet.īut normally, octopuses range from 12-36 inches and weigh 6.6 -22 lbs. The smallest squid is the pygmy squid, which only grows about an inch long. At the same time, you can also find a giant squid reaching up to 66feet. SizesĪn average squid can grow to be very large, with some squid species reaching up to 60 feet in length. Octopuses also have a perfect sense of taste. They rely on their sense of touch to find food and mates. Octopuses, on the other hand, have very poor eyesight. They also have a light-sensitive organ on their long tentacles to detect movement. Squid have excellent eyesight and can see in bright light and dark water. Squid and octopuses have very different senses. Though most adult octopuses, male octopus, and squid die soon after mating, the females often live to take care of their eggs. The larger squid found in the deep ocean can live up to 15 years. Some species of squid can live up to ten years. The lifespan is determined by the species of squid or octopus. The average lifespan of a squid is five years, while the lifespan of an octopus is only three years. Squids lay their eggs in a safe place and then abandon them. When a male and female squid meet, they will wrap their arms around each other and spin around in a mating dance. The squid mate in larger groups, and the male will often mate with more than one female. The female octopus then guards her eggs until they hatch. Once the female squid lays eggs and attaches them to a hard surface using a sticky thread, they form a beautiful decorative string and look like a work of art. The male octopuses transfer sperm using a specialized arm called a hectocotylus. The octopus’s arms are all the same length and have suckers on them, which they use to catch prey and move around. ![]() The squid’s tentacles are longer than its arms and have one or two rows of sucker rings on them, which they use to catch prey. Squid have eight arms and two tentacles, while octopuses have eight long arms and no tentacles. One of the biggest differences between octopus and squid is their appendages. The octopus also has chromatophores in its skin, which it uses to change colors and camouflage itself.Ī squid has a triangular head and two fins that runs along its entire body, unlike octopuses that have a round head and no fins except one specie called the Dumbo octopus that has fins. The octopus has no internal skeleton and hence has a soft body that can squeeze through tight spaces. The squid also has a sharp beak made of chitin, which it uses to tear apart its prey. The octopus has a shorter, compact body with eight flexible arms and no octopus tentacles. Squids have a long, tubular body with eight arms and two specialized tentacles used to catch fish. Cuttlefish can be cooked for longer, so it works great for stews, paellas, and risottos.There are some obvious physical differences when looking at a squid and an octopus side by side. On the other hand, squids use their eight arms lined with suckers and two tentacles to reach and capture their prey. On the other hand, octopuses grow to reach anywhere between 0. However, the smallest species of squids such as sepiolid are less than an inch in length. ![]() Squids can grow to reach anywhere between 23.5 inches to almost 66 feet in length. Octopus makes use of its eight sucker lined arms to get hold of its prey. Although squids are generally smaller compared to octopuses, there are squids which are extraordinarily large. You can cook it the same way as you would cook a squid, but the taste of it will give a surprising difference. Generally octopuses live in dens, whereas squids are commonly found in open seas. The taste is more flavored than squid but not as rich as the octopus. On the cooking and food side, cuttlefish is in the middle of squid and octopus. Octopus and squid have rounded eyes, but cuttlefish have eyes in the shape of a W.įinally, looking at the cuttlefish body, they are fatter and rounder whereas squid has a more elongated body also called a “tube.” Cuttlefish also is more meaty with a thicker body. They move using wings on the sides of their bodies.Another way to tell the difference is by looking at their eyes. If you look at them, octopus and squid are fast predators, whereas cuttlefish are slower. The fact that cuttlefish have an internal shell called “cuttlebone” make them the slowest and least flexible of the three. The main difference between cuttlefish and the two others is their shape and looks.
