1. Are octopus, squid, and cuttlefish the same species? What are the differences? Can these be kept in fresh water?

Squid, cuttlefish and squid are the same;

Octopus and octopus are the same;

The tubule cannot be said to be the same as the squid. It can only be said to be a type of squid, characterized by its small body and slender trunk. It is also called soft fish.

Squid, cuttlefish and octopus all belong to the class Cephalopoda of the phylum Mollusca

Squid, also known as cuttlefish and calamari.

Cuttlefish, also known as squid and cuttlefish, belongs to the same order as squid.

The meat of squid is more delicious than that of cuttlefish. Its head and trunk are narrower and longer than those of cuttlefish, especially the end of the trunk is very similar to the tip of a javelin, so it is called squid.

Octopus, also known as octopus, belongs to the order Octopoda.

Both octopuses and cuttlefish have ink sacs that release ink. The biggest difference is that octopuses only have 8 arms, and the suckers on their arms have no handles or tooth rings.

2. Do tiger groupers live in salt water or fresh water?

Tiger fish is a kind of wide-ranging freshwater fish, with a suitable growth temperature of 1-40℃, and a habit of feeding and growing all year round. Its pH value adaptability range is 6.5-8.5, and it shows a high degree of adaptability and tolerance when oxygen drops to 3.8mg per liter.

3. Methods of protecting squid

They will not give up their bodies voluntarily. However, they may regenerate their limbs. Wandering and spraying ink are their usual ways of self-preservation. Ink has a certain anesthetic effect. Some large squids, such as the giant squid, will choose to fight. The suckers of the squid are serrated, and the giant squid is very lethal. The keratin beak of the parrot's beak is also very powerful.

4. I want to know whether freshwater cuttlefish or saltwater cuttlefish is better.

Freshwater dried cuttlefish is actually usually called "light dried", which is a dried product produced by the sweet sun-drying method. Sweet sun-dried cuttlefish is made naturally by sea breeze and sun-drying without adding salt, which keeps the freshness of the cuttlefish and has a more natural and pure taste. Salted sun-dried cuttlefish is cheaper and has a longer storage time because salt is added during the drying process, but the taste is not as good as sweet sun-dried cuttlefish.
