Those free-swimming jellyfish in the sea don't start out in that familiar medusa form, but rather start as sessile and asexual polyps. Now, researchers have discovered what triggers that ...

Jellyfish are an ancient and successful group of animals. An in-depth look at the genome of the moon jelly, Aurelia aurita, shows that it uses a common set of genes to transition between polyp and ...

Scientists have developed a robot that uses resonance to propel itself through water in the same style as an Aurelia aurita jellyfish, which is the natural world’s most efficient swimmer. The research ...

The first in-depth look at the genome of a jellyfish -- the moon jelly Aurelia aurita -- shows that early jellyfish recycled existing genes to gain the ability to morph from polyp to medusa. Jellyfish ...
