Molecular switch: Researchers unravel mystery of jellyfish proliferation

Scientists have deciphered the mysterious life cycle of jellyfish - and promptly warn to use the new knowledge as a weapon against the animals.

The invasions of jellyfish in the North and Baltic could can be curbed by new findings. Researchers have found claims to exactly how a polyp from a jellyfish is - and also found a potential way to prevent the mass reproduction of the animals .

 The jellyfish is common in the North and Baltic Sea and in the Atlantic. It is pocket-sized and non-toxic, grows in the spring and dies each winter .

It was already known , such as arise from polyps jellyfish : From an egg cell first forms a larva and from a Polyp . The polyp is stuck, about to lock gates , eats and can not move . He decides dependent on temperature towards the end of winter, that made ??him jellyfish arise : He keeps small rings from , from which grow over the spring, summer and fall of jellyfish that produce sex cells and then die . The cycle then begins again : From fertilized eggs larvae and emerge from polyps that can reproduce asexually .
