Interesting facts about oysters

Oysters (Latin Ostreidae) are a family of marine bivalve molluscs. They have a very characteristic asymmetrical irregular shell. One of the most popular among the commercial groups of marine invertebrates.

Oyster Facts:

1. Did you know that oysters, which, like most other individuals, have two sexes, can change it. This can happen several times during the life of an oyster, under the influence of various factors. It's funny that usually oysters begin their life as "men", and after being well fed and ready to produce offspring, they become "women." Therefore, it is even possible for an oyster to fertilize its own eggs.

2. Did you know that the rule that oysters should be eaten only in the months with the letter "P" in the name became obsolete at about the same time when artificial breeding of oysters became widespread. Now the months when oysters produce caviar can be changed at the discretion of the manufacturer, and besides, there are non-caviar-producing oysters. Although, there is another explanation for this rule - oysters on the ruins really spoil faster in summer.

3. Do you know that the story that oysters squeak when they are poured with lemon juice apparently comes from the story of A.P. Chekhov's "Oysters" - this is how the hero of the story imagines an oyster:

“I imagine an animal that looks like a frog. The frog sits in a shell, looks out from there with large shining eyes and plays with its disgusting jaws. I can imagine how this animal is brought from the market in a shell, with claws, shining eyes and slimy skin ... The children are all hiding, and the cook, grimacing with disgust, takes the animal by the claw, puts it on a plate and carries it to the dining room. Adults take it and eat it… eat it alive, with eyes, with teeth, with paws! And it squeaks and tries to bite the lip ... "

4. Back in the early 19th century, both in France and in England, oysters were considered the food of the poor, who did not have enough money for meat. However, the uncontrolled catch of oysters led to their sharp decline in nature, and in the second half of the 19th century they greatly increased in price, becoming a delicacy.

5. If you take an oyster egg and place it in an aquarium with distilled water that does not contain calcium, the oyster grows no different from the controls, and its valves will also consist of almost pure calcium.

6. The first indicator of the freshness of oysters is a tightly closed shell: if there is even a tiny gap in it, then the oyster is rotten.

7. Oyster meat contains protein, fat, carbohydrate glycogen, minerals (iron, zinc, copper, calcium, iodine, phosphorus), niacin, as well as vitamins B1, B2, B12 and PP. Only 6 oysters - and the body's daily need for iron and copper is provided!
