[10], This discovery led to great advancements in the field of medicine because it allows for further understanding in treatments and medical diagnoses through research in cells and bacteria.[11]. Dolphins are known to play frisbee with jellyfishes but they have never been observed to eat them.

Food: For the most part these guys consume other soft bodied organisms like themselves. 9 What can Aequorea victoria green fluorescent protein be used for? Osama Shimomura first discovered GFP and in 2008 he and his colleagues Roger Tsien and Martin Chalfie were awarded the 2008 Nobel Prize in Chemistry for both the discovery and development of the green fluorescent protein. They are mostly transparent but under ultraviolet light there is a bioluminescent green ring around the bottom of their umbrella. Jellyfish practically eat whatever passes in the water and can fit well in their mouth, including krill, shrimp, and small fish. Jellyfish stings can be painful and sometimes dangerous to humans.
