Octopus, squid and cuttlefish, people jokingly call them the "Three Soft Brothers". Many people can't distinguish and confuse it, so do you know which of the three brothers in the picture below?
Want to know my name?
I have an escape trick, when I encounter an enemy, I quickly spew out ink from my body, blacken the surrounding sea, and I can escape
Next, let me introduce myself!
Cuttlefish, the real name of the squid, also known as squid, cuttlefish or flower branches.
Cuttlefish are mollusks of the order Squid in the order phytocephalopoda. When the squid encounters a strong enemy, it will use "inkjet" as a method of escape and wait for the opportunity to leave, so it has names such as "squid" and "cuttlefish". They have pigmented sacs in their skin that change color and size as "mood" changes. Squids can jump out of the sea and have amazing aerial flight capabilities. It is characterized by a thick lime inner shell (squid bone, cuttlefish bone, or sea mantis, called "cuttlefish plate" in adults, which can be used for medicine).
Let's introduce it to you
Let's have the other two of the "Three Soft Brothers"!
Octopus, also known as octopus, stone dwelling, dead cow, we honor adults call it "eight sheaths" or "eight sheaths".
Octopus belongs to the mollusks of the order Octopuscephalus, octopus in the octopus family. Because it has eight wrists on its head, and there are membranes connected between the wrists, the length is different, and there are 2 rows of sessile suction cups on the wrist, so it is called "eight wrists". It is a marine animal. Not a fish. Not only can an octopus spray ink six times in a row, but like the most flexible chameleon, it can change its color and structure like a stone covered with algae, and then suddenly pounce on its prey, which has no time to realize what is happening.
Squid , also known as Jurchen , Soft fish , or Gun Squid , is an animal of the mollusc Phytocephalus pipe squid eye-opening suborder.
The body of the squid is slender, long and tapered, with more than a dozen tentacles, two of which are longer. There are suction cups at the front of the tentacles, and there are tooth rings inside the suction cups, which are wrapped around the tentacles when preying on food. It prefers to gather in groups, especially in the spring and summer mating and spawning periods. Gun squid is a ferocious carnivore, feeding mostly on small pelagic species such as small male fish, sardines, hmong and krill, and also preys on their kind. The gun squid itself is also an important bait for tuna, mackerel, striped fish and seabirds.
<h1 class="pgc-h-arrow-right" Data-track="27" > the difference between octopus, squid, and cuttlefish? </h1>
1. The body structure is different
Octopus has eight wrists, squid and cuttlefish have ten wrists.
Octopus has a soft body, squid grows cartilage, and cuttlefish have hard bones.
2. The appearance and shape are different
Seeing an octopus we can associate it with a small octopus ball, whose body is sac-shaped and looks like a ball;
The body of the squid is narrow and long, like a pipe, and the cross-section is circle-shaped;
The body of cuttlefish is relatively flat and very wide.
3. Life habits are different
Octopuses generally crawl along the coastal bottom with suction cups in their wrists, and their movements are very slow; Squid and cuttlefish swim rapidly in the sea.
Octopus is a nocturnal animal, very sensitive to light, like to stay in the dark environment, fishermen often throw special clay pots into the sea, and then calculate the time, invite the king into the urn, wait for the octopus to drill into the jar, throw themselves into the net;
Squid and cuttlefish like to shine, and fishermen use their habits to hang fish lanterns on fishing boats and wait for them to flock to them, and then catch them all.
4. Different ways of eating
Octopus can be eaten raw or cooked, and raw food is especially good;
Squid and cuttlefish must be cooked before eating, because they have a polypeptide component in their bodies, if they are not cooked thoroughly, they will often make the gastrointestinal movement of diners disordered and cause abdominal discomfort. In addition, aquatic products such as squid are cold in nature, and people with a weak spleen and stomach should also eat less.
