This invertebrate has special characteristics that make it unique, and has even aroused the interest of science. Although their sting is lethal for their prey, there is no major risk for humans. Coral has been found to recover from bleaching induced by stress in cases when the condition is not severe. This marine invertebrate achieves such an expansion of its mouth that it can swallow other jellyfish or prey twice its own size. When jellyfish venom enters the body through a sting, it reacts with the blood, leading to a dangerous . New free-living jellyfish can grow from these polyps through asexual reproduction.

They live almost exclusively underneath and among the tentacles of larger species like the compass and cannonball jellyfishes, and derive most of their sustenance by sharing the food caught by the jellies and also by nibbling from their gonad tissues which is rich in protein. The eggs and spermatozoa mature daily in the medusa gonads, given enough food, and are free-spawned into the water column in response to a daily light cue, where they are fertilized and eventually settle out to form a new hydroid colony. The penguin spends half of its life underwater. Another technical predator of theirs would be humans, as they are used to conduct research in gthe medical field. The lion's mane jellyfish ( Cyanea capillata) is the largest known jellyfish species, able to grow up to six and a half feet long.

In fact, an article from the Complutense University of Madrid explains that one of the reasons why jellyfish are closer to beaches is the fracture of the temperature and salinity barrier between the open sea and the coast. The visual signal that GFP provides allows scientists to probe protein activity, such as when and where proteins are produced and how different proteins or parts of proteins move The crystal jelly lives in pelagic waters in the Pacific Ocean from Vancouver, British Columbia, to central California. The Crystal jelly jellyfish is a fascinating animal, as it possesses a protein that has been widely used in the study of biological processes in human cells. They only consist of three layers: the outer layer known as the epidermis, a thick elastic and leased substance called mesoglea, and an inner layer called gastrodermis.
