Thanks to Wyatt Patry of the Monterey Bay Aquarium we now have Cnidaria including Cephea cephea! These Cephea cephea or Crown jellies are from Japan. The aquarium's page on Crown jellies can be seen here.
This is a page from my sketchbook of some more info about Cephea cephea.
Below is a video of some polyps. Freya believes that the lighter color one is in the Scyphoistoma stage and the darker color one may be in the Strobila stage closer to strobilating. Notice that the ephyra seen in the next video is also a darker color. Cephea cephea undergo monodisc strobilation so only one ephyra and medusa will result from each polyp as opposed to polydisc strobilation where many ephyra result from one polyp.
This is the only Cephea cephea ephyra we currently have. Hopefully more are to come!
