In the sea, jellyfish are the most common, but also the most feared animals. Every typhoon day, you can find a large area of jellyfish in the inlet bay, they are as stunning as a white, pink crystal umbrella, but beautiful creatures are always extremely dangerous, jellyfish perfectly illustrate this sentence. Today, Xiaobian will introduce this common marine life in detail for you!
Jellyfish are actually jellyfish, the local dialect is also called "white skin", as for the origin of the name of the jellyfish, there is really not much information to explain this. In our country, jellyfish live mainly on the southeast coast. Jellyfish jellyfish-shaped bodies take on the shape of bells or inverted bowls, or umbrellas. Generally speaking, the part that protrudes outward is called the jellyfish head, also known as the umbrella surface, the lower edge is connected with tentacles, and a circle of membranous structures is extended inward, called "margin membrane", except for the part of the head, we can call it jellyfish skin. It is worth mentioning that the marginal membrane is a unified feature of the hydra jellyfish.
Don't look at the little jellyfish soft and weak like a beach of plastic bags, but as stinging animals, they are really carnivorous. Jellyfish feed on plankton, small crustaceans and even smaller fish. Food, as a stimulus, allows animals such as jellyfish to stretch out their tentacles on their own, release spiny sacs to wrap around their prey, and then paralyze and kill the prey through venom, and then send it to the mouth for a good meal. Interestingly, since stingrays do not have formed respiratory and excretory organs, jellyfish can only rely on body wall cells to excrete. In addition, the water flowing in and out of the stomach cavity can bring in fresh oxygen and take away excrement.
Jellyfish reproduce in a way that is similar to that of bacteria, and they are interesting "budding" reproduction. When the jellyfish sprouts, it protrudes from the base of the body through the body wall and the stomach cavity, and the protruding part slowly grows new tentacles and mouths, which are new shoots, and then the buds are separated from the mother to form a new individual. Other hydra-type organisms, such as sea anemones, that are similar to jellyfish, can multiply and multiply vertically. Of course, the strong cell division ability is also doomed to jellyfish must have a very strong regenerative ability, it is said that the jellyfish cut into several segments, as long as there is a certain time and suitable conditions, each segment may grow into a new jellyfish individual, how, is not very magical?
Of course, for us, the most important role of jellyfish is still to eat. Jellyfish eating method is actually very simple, the captured jellyfish should be pierced with sharp objects through the umbrella body, and then soaked with alum, lime and other substances, and then squeezed dry of its water, so that three times, in order to drain the jellyfish toxin, and then washed and salted and marinated. The latter approach depends on how you eat it, how you want to eat it and how you do it. It should be mentioned that if you are accidentally stung by jellyfish, do not be sad, do not be anxious, do not rinse with fresh water, because fresh water will promote the release of toxins from thorn cells, you must first use towels, clothes, and even sediment to wipe off the tentacles and venom adhering to the skin, and then rinse with seawater or alkaline solution, after simple treatment, if it is still very serious, please send it to the hospital for treatment in time.
