This Jellyfish Isn't a Jellyfish at All — And Its Real Name Will Surprise You

That's right. You may get used to sea cucumber along the seafloor, it looks good ... it looks like multicolor cucumber, they somehow find a way to the bottom of the ocean

But Pelagothuria natatrix is ​​different. In the sea cucumber beauty contest, I definitely win

The small transparent body is surrounded by the surrounding tentacle umbrella. I sit in the center of the umbrella with that mouth. Unlike a sea cucumber, it does not move along the ocean floor.

Instead, swim in the water picking jellyfish like food on the nearby particles.

Scientists have been confused about this creature for many years because it is the only sea cucumber like that

In addition, it has been found in three different seas, but it is very rare. Evidence of this animal dates back to 1894, but the only picture of a swimming sea cucumber comes from the mission of NOAA in 2011.

So at the beginning of this year, NOAA 's Okeanos Explorer discovered the world' s first video that Pelagothuria natatrix is ​​swimming in the sea. This is a big problem.

This video is wonderful. This is the only sea cucumber in the world devoted to swimming, fascinating, high quality looks. Team ROV or remotely controlled vehicle gently caught animals near Howard Island in Australia.

E / V Nautilus also shot rare species shots. Thanks to its delicate tentacle opening and closing, you can see that nearby floating particles may become a cucumber diet

You can find shots of more beautiful swimming sea cucumbers with the official account of NOAA Ocean Explorer.

This jellyfish lives in the aquarium of SC Riverbank Zoo. Since I hope that I took a photo of the brand name, it seems that it is a bit less than the jellyfish you see in the aquarium, as you can teach you what kind of jellyfish it is . After some research, it may be Cassiopeia Andromeda. If you are reading this article and you know the name of this little guy, please let me know in the comments, I will update this post!

Given that jellyfish is a common name, mapping to biological groups is inaccurate. Some authorities refer to comb jelly and certain salmon jellyfish, but other authorities claim they are not jellyfish, and they believe that certain group of drugs should be restricted I will. Jellyfishes are not branches because they contain most of Medzozo, except for some hydrozores. The existence of the medusozoan group included by the authorities is indicated by the existence of references in the following phylogenetic trees. Include the jellyfish name in bold in English; if possible, the existence of a named citation indicates that at least the species in that group is called jellyfish

In the early 1960s, Osamu Shimomura researcher noticed a jellyfish called Aequorea victoria on the coastline of Washington State. It can irradiate (UV light). Shimomura isolated the beautiful green protein he observed and named it green fluorescent protein (GFP). The GFP found in Aequorea Victoria jellyfish is very weak and difficult to detect, but when these jellyfish gather in a large group it is very eye-catching.

Jellyfish has been found worldwide from surface water to deep sea. Lepidoptera ("real jellyfish") is merely a marine creature, but some aquatic animals with similar appearance live in freshwater. Large, usually colorful jellyfish is common in coastal areas around the world. Most species of medusa grow rapidly, mature within a few months and die soon after reproductive, polyps attached to the ocean floor may last longer. Sea otters will walk around the ocean for at least 500 million years, probably over 700 million years, becoming the oldest multi-organ faculty.
