Jellyfish are unique living organisms that inhabit most of the seas and oceans. The smallest jellyfish are no larger than a wasp, the largest are amazing.
Instructions
Step 1
The largest, or more precisely, the longest animal on the planet, is the giant cyanea jellyfish, or hairy cyanea. This unusual creature is also called the lion's mane. In 1865, a huge cyanea was washed ashore in Massachusetts Bay. Its dimensions were amazing - the diameter of the dome of this jellyfish was two hundred twenty-nine centimeters, and the tentacles stretched thirty-seven meters.
Step 2
Zoologists believe that cyaneans can reach a dome in diameter of two and a half meters, most likely, in the largest specimens, the length of the tentacles may exceed thirty-seven meters documented in 1865. It should be noted that blue whales, which are considered the largest mammals, reach a maximum of thirty meters in length, which makes cyania a kind of record holder.
Step 3
In Latin, cyanos means blue and capillus means capillary, or hair. That is, Cyanea capillata literally translates as "blue-haired jellyfish." There are several species of this animal, all of them are inferior in size to the giant "lion's mane".
Step 4
The poison of this jellyfish is strong enough, but not fatal for a healthy person. It causes discomfort of varying degrees of intensity, but almost never leads to death. The problem is that cyanea has a lot of tentacles, they are very long, so if you get entangled in them, increasing the contact area, you can seriously suffer.
Step 5
The Nemopilem jellyfish is another huge creature. It reaches two meters in diameter. These jellyfish are mainly found in the East China, Yellow and Japan Seas. Nemopilemus differs from cyanea in a heavier and more massive dome and short tentacles. It should be noted that non-pilems are eaten in Japanese, Chinese and Korean traditions.
Step 6
The venom of this jellyfish can cause serious burns and breakdown of the muscular and nervous systems of a person, but it is not fatal, as is the case with cyanea venom.
Step 7
The life cycles and principles of reproduction are almost the same for non-pylem and cyanea, both jellyfish live only a year. The short life of these amazing coelenterate giants is due to the incredible growth rates - both cyanea and nemopilem gain in weight up to ten percent daily. These jellyfish feed mainly on zooplankton, filtering sea water through a network of tentacles, they kill or simply paralyze small living creatures with their tentacles, which they then consume.
