Sea Jelly

"Sea Jelly"


( Lion's Mane or hairy cyanide )

So the American aquarists call jellyfish. These amazing creatures appeared 650 million years ago, and still live in all depths of the ocean and even in fresh water.
   The word (jellyfish) in almost all languages ​​of the world sounds the same. The brain and sense organs in the jellyfish are absent, their simplest nervous system, located on the epidermis, is able to determine only light and smell, as well as the touch of another being.
    Jellyfish do not have a respiratory system: their skin absorbs oxygen directly from the water. These marine residents are more than 90% water, and their umbrella is a gelatinous material surrounded by 2 layers of cells. In the jelly-like and transparent body of the jellyfish there are as many as 24 eyes. The lower part of the jellyfish is called the bell. As a source of food jellyfish use zooplankton, eating including eggs and larvae of some species of fish.
    The largest species of jellyfish on the planet is called "Lion's Mane" or hairy cyanide. In 1870, a jellyfish was thrown ashore in the Gulf of Massachusetts, the diameter of the bell was 2.3 m, and the length of the tentacles reached 36.5 m.
    The most dangerous is a jellyfish sea wasp, or jellyfish-box. Each tentacle of this creature contains about half a million poison glands that resemble harpoons with needles at their ends. The poison of this jellyfish is capable of killing a person in 3 minutes, it has multiple effects, simultaneously affecting the nervous system, heart and skin.

     Even remote tentacles remain dangerous until the very destruction with time, and even being dried can restore their properties when moistened. The sea wasps feed on prawns and small fish, and themselves, in turn, serve as prey for sea turtles: these are the only creatures not sensitive to their poison.
    Venom medez not only kills, but also cures. Even in the Middle Ages, jellyfish were used to make laxatives and diuretics, and modern pharmacology created medications based on the jellyfish venom, which treat lung diseases and regulate blood pressure.
    In Japan, Korea and China prepare dishes from jellyfish for over 1700 years. They are recommended for high blood pressure and other diseases. In Thailand, they make noodles. In China, they are salted, or dried (the result is something like dried mushrooms or thin brown pancakes). In 2006, during the mass reproduction of large jellyfish off the coast of Japan, these jelly-like creatures went even to stuffing for pies, and soups were cooked from them. The jellyfish is full-fledged and contains 17 amino acids, including a full set of irreplaceable ones.

Dream Factory Today, on the southern slope of Mount Mount Lee in Hollywood, the famous Hollywood inscription flaunts. It appeared on July 13, 1923 and looked a little different. At that time, the letters were the word Hollywoodland, and it was not a commemorative sign, but advertising of new residential neighborhoods in Los Angeles. The height of each letter was 15 m, and the width - 9 m. The lighting of the inscription consisted of 4 thousand bulbs. The owners of the inscription were first going to dismantle it after 1.5 years, but it acquired such fame that it was left. The last part of the word - Land - was removed only in 1949.     By 1978, the letters had become unusable, and required immediate restoration. Then the owner of the Playboy magazine, Hugh Heffner, announced an auction during which each letter acquired its own sponsor.     The next renewal of the sign took place in November 2005 and was a complete repainting of the letters.     The Hollywood Walk of Fame wa

Cock   with   curling In the Chinese mountain village of Sinzesun, a farmer lives, in the poultry house of which lives the world's only curly-haired cock. According to the story of the farmer at first everything was like that of other birds, the cockerel hatched out of the egg at the right time and grew, no different from other chickens. When the feathers began to form in the birds, the farmer noticed that this rooster had a strange appearance and did not fit tightly to the body. With age, feathers curled more and more, in the end, the cock began to look as if he had been given a perm.
