What type of animal is a jellyfish?

Jellyfish belong to the class of coelenterates. In addition to the typical characteristics of coelenterates, such as a primitive digestive cavity, being an invertebrate and having radially symmetrical bodies, jellyfish also have other characteristics of coelenterates, such as a fixed shape, no brain, and a nervous system.

Jellyfish, a Scyphozoan, Crossozoan, Cubozoan, is an important plankton in the aquatic environment and a very beautiful aquatic animal.

The body shape of a jellyfish is like a transparent umbrella. The diameter of the umbrella-shaped body varies. The diameter of the umbrella-shaped body of a large jellyfish can reach 2 meters. There are some whisker-like tentacles growing on the edge of the umbrella-shaped body, and some tentacles can be as long as 20-30 meters.

The main component of the jellyfish body is water, and it is composed of two germ layers, the inner and outer germ layers. There is a very thick mesoglea layer between the two layers, which is not only transparent but also has a floating function.

What is the living environment of jellyfish like?

Jellyfish are widely distributed in the ocean, and different jellyfish have different adaptability ranges to changes in seawater temperature and salinity. Some species can only adapt to changes in temperature and salinity within a narrow range, so jellyfish with a narrow distribution can be used as indicator species of water currents. For example, the Arctic jellyfish is only distributed in the Arctic Ocean and can be used as an indicator organism of cold currents.

Can jellyfish be eaten?

Most jellyfish are poisonous, and only some are edible, such as jellyfish and moon jellyfish. Jellyfish contain low fat, inorganic salts, and protein, but only a small amount of protein and gelatin are left after cooking, so the nutritional value is not very high. Jellyfish is generally cooked in a cold dish, and the taste is crisp and smooth.

Although jellyfish can be eaten, only jellyfish and moon jellyfish are edible among jellyfish species. Other jellyfish cannot be eaten because most jellyfish are highly toxic. The poisonous jellyfish include Portuguese man-of-war, lion's mane jellyfish, Irukandji jellyfish, Australian box jellyfish, etc.

Jellyfish contains a relatively low amount of fat, and also contains nutrients such as protein and inorganic salts. However, most of the jellyfish body is water, and after cooking only a small amount of protein and gelatin remains. Therefore, the nutritional value of jellyfish is not very high and is not as good as other seafood products.

The cooking method of jellyfish is generally to mix it with cold food, so that you can taste the taste of jellyfish. Among them, jellyfish is generally used for mixing with cold food, which has a crisp and smooth taste and is popular with many people. Jellyfish can also be pickled into jellyfish skin. The pickled jellyfish has a salty and fresh flavor and a chewy texture.
