What kind of animal is a jellyfish

Jellyfish are aquatic animals. Jellyfish are important planktonic organisms in aquatic environments, including cnidarians, mantle jellyfish, cross jellyfish, and cubozoans. The jellyfish is a very beautiful aquatic animal. Its body is shaped like a transparent umbrella, and the diameter of the umbrella varies from large to small, with the umbrella of a large jellyfish reaching up to 2 meters in diameter. The edge of the umbrella body has some whisker-like tentacles, some tentacles can be as long as 20-30 meters.

The main component of the jellyfish body is water, and by the inner and outer two embryonic layer is composed of two layers, there is a thick layer of gelatinous layer between the two layers, not only transparent, but also has a floating effect. They are in motion, the use of the body of the water jet reflex forward, from a distance, like a top of the round umbrella in the water quickly drifting; some jellyfish umbrella body also has a variety of colors pattern, in the blue ocean, these swimming colorful jellyfish appear very beautiful.

Jellyfish luminescence principle

Jellyfish light source and other animals are different, other animals are mostly fluorescein, luciferase through the catalytic effect of oxygen, and thus luminous. But the jellyfish light is a kind of magic protein called Ekwerin, this kind of protein encounter calcium ions can send out a strong blue light. According to scientists, each jellyfish contains about 50 micrograms of light-emitting proteins, which means that the jellyfish is relying on it to emit light. For researching the principle of jellyfish luminescence, Shu Shimomura and others won the 2008 Nobel Prize in Chemistry.
