Jellyfish are important plankton in the aquatic environment and a very beautiful aquatic animal. There are quite 250 species of jellyfish in the waters of the world, and that they are distributed in waters all over the world.
Whether it's tropical waters, temperate waters, shallow waters, oceans with a depth of about 100 meters, and even freshwater areas, there are traces of them.
Jellyfish existed as early as 650 million years ago, even before dinosaurs. The main component of the jellyfish body is water, and some jellyfish also emit light.
This has always been a very important research topic, and some people have even won the Nobel Prize for their research. Here are three of the most beautiful jellyfish in the world.
1. Eros Belt Jellyfish
This jellyfish is a small group of jellyfish-like marine invertebrates. They are not cnidarians. This jellyfish is not good at swimming, they can only rely on the energy of the current to "go with the current".
The transparent body makes the Eros belt jellyfish almost "invisible" during the day, while at night they emit soft bioluminescence. Unlike other jellyfish, Eros belt jellyfish can grow up to one meter in length and about 5 cm in width.
The jellyfish is transparent throughout, with a soft violet hue and iridescent fringes that look very much like a large transparent ribbon.
The jellyfish of the god of love is also known as the belt of Venus. They float slowly and gracefully in the sea. Indeed, only the god of love is qualified to wear such a beautiful ribbon.
2. Rainbow Jellyfish
The rainbow jellyfish was one of the top ten new species discovered by National Geographic in 2009.
Larger, reaching 13cm in length, they glow, and this glowing new species of jellyfish has been discovered off the coast of Australia. An ongoing study has shown that these jellyfish do not sting.
Jellyfish expert Lisa Gershwin found the jellyfish near a breakwater off the coast of Tasmania, Australia, and captured it in a photo tank, a small aquarium that is convenient for photographing marine animals.
This jellyfish does not emit light itself like other light-emitting creatures. The iridescent light emitted comes from the reflection of light by the cilia.
Cilia are tiny hair-like projections that help jellyfish swim through water by draining water. While the rainbow jellyfish is already the 159th jellyfish Gershwin has discovered in Australia, she still thinks it's a very exciting discovery.
Gershwin said the newly discovered jellyfish is a member of the Ctenophora family, a bizarre family we know very little about.
3. Moon Jellyfish
There are many species of jellyfish, and it is impossible to distinguish them by their appearance alone. It must be analyzed by genetics. This jellyfish is kept in many aquariums.
The jellyfish body of jellyfish is transparent, generally 25-49 cm wide, and they live in the Atlantic, Pacific, and Indian oceans.
The moon jellyfish has a large number of natural enemies, including sunfish, leatherback turtles, seabirds, and some parasites will also attack the moon jellyfish.
The moon jellyfish survives and reproduces for a few months before dying naturally. Rarely live for more than 6 months in the wild, but some can survive for several years in the aquarium.
