Molecular evidence indicates that the Anthozoa are the basal cnidarian group, but they lack both the medusa stage and well-developed muscle. So, there is active debate as to whether the molecular ...

Perhaps complexity, in the form of a medusa stage, existed in early cnidarians but was lost in all related groups living today except jellyfish. Either scenario would produce a similar genomic ...

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.

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. “Our ...

They compared these distinct patterns of gene expression to those observed in 11 different cnidarian species ... active in the moon jellyfish's medusa stage. But moon jellyfish have a special ...

Some animals can regenerate their whole bodies, including phyla Cnidaria such as jellyfish ... Jellyfish have three life-cycle stages; larvae (planula), polyp, and medusa stage (the jellyfish ...

The medusa is the mobile, sexually reproducing phase of the jellyfish life-cycle, which includes several inconspicuous developmental stages. Among these is a minuscule, tentacle-bearing form ...

An adult jellyfish is known as a medusa. Jellyfish belong to a group called Cnidaria, which also includes sea anemones ... This illustration shows the different life stages of Turritopsis jellyfish.
