Jellyfish and scientists

Surely the relationship between Jellyfish and Scientists is a rocky one. In the 90's, it was discovered that the Green fluorescent protein which made several jellyfish glow could be used to mark genes to find out which genes trigger a variety of diseases and attributes. See this article for more information about the Nobel Prize won for perfecting this technique.

But now Jellyfish are taking over a large number of bays and oceans near big cities. These areas,, known as "dead zones" are full of pollution and fertilizer run-off which have killed off local fauna and left the regions wide open for jellyfish who thrive in a low oxygen, low plantlife area. They can survive in very hot water, very cold water and very dark water. And for many, killing them triggers the release of billions of eggs and sperm, guaranteeing their future generations. Read about it here.
