Most people, when they think about jellyfish, they think of only one or two types of jellyfish. With the Confort & Flash tickets,save time and avoid the line ! Perhaps the similarities between the moon jellyfish genome and "higher" animals demonstrates that the Cnidaria originally had a medusa life stage, which animals like corals and sea anemones lost. It is related to the large jellyfish we often see near our shores, called 'lungs of the sea', Rhizostoma pulmo.

They are both beautiful—the jellyfish with their pulsating bells and long, trailing tentacles, and the comb jellies with their paddling combs generating rainbow-like colors. "In many ways, the ancient oceans in the late Precambrian are very much like what the modern oceans will look like in the near future," Gold said "meaning studying how jellyfish evolved in the past can tell us about their potential impact on the future.". In addition to questions of evolution, the Aurelia genome will prove valuable in many other areas of biology, Gold said. Australian researchers have described them as a "perfect food", … +33 (0)5 46 34 00 00. An improved understanding of Aurelia genetics could offer new ideas for controlling the blooms. Get premium, high resolution news photos at Getty Images To accomplish this, the medusa life stage often co-opts existing developmental gene networks and cell types present in polyps, the researchers found.
