- Aurelia: Sexual stage dominates, makes up most of its life cycle. Has Strobila and produces ephyras - Obelia: asexual stage dominates, polyp. October 23, 2015 As much as I love working with Aurelia, the documentation can be confusing for newcomers to the framework (forgivable considering it is so new and evolving). However, the planula may undergo vegetative multiplication or develop directly into an ephyra shortly after settling , without the formation of a scyphistoma .

Most people are only familiar with full-grown jellyfish—the eery, translucent, bell-like creatures that occasionally wash up on sandy beaches. Take a look around a 4000 litre jellyfish breeding facility.

The jellyfish, Aurelia, like almost all Scyphozoa, have a life cycle that is composed of an alternation between two main stages: the active jellyfish or medusa stage and the sessile polyp stage. Eggs released by females pass out through the mouth and become lodged in pits on the tentacles. Compare the life cycles of Obelia and Aurelia.
