The Life cycle of the Moon Jellyfish Aurelia aurita
Starting more than twenty years ago I photographed the developmental stages of marine organisms against a black background, with the idea that I would assemble them one day into a single composition. I tried to do this in the darkroom back then, but that never led to any satisfactory results. Now with Photoshop and a large collection of digitized life cycle stages, the old idea can be realized. This is the first one in the series. The large photo below is an image map: hover with your mouse over the picture and the following explanations will appear: ephyra, juvenile medusa, rhopalium (sense organ), strobila, ephyra budding off, scyphistoma (polyp), adult medusa, scyphistomae developed through budding (asexual reproduction), planula, settled planula, development of planula into scyphistoma, mouth, stomach, radial canal, oral lobes, tentacles, gastral filaments, click for more jellyfish, copyright Robert Brons 2013 All rights reserved.

Hi Robert! Than you so much for this great post and graphic. I host a website called jellybiologist.com, and am studying for my PhD on development in scyphozoans. I'm giving a talk this January, and would like your permission to use this figure. It's for a scientific audience and won't be distributed on the web. Thanks so much again!
BeantwoordenVerwijderenHi Robert,
BeantwoordenVerwijderenI am a biologist and a designer of educational product at the Montreal Biodome (zoo and aquarium in Canada). I am currently working on a special event about jellyfish in June. Your photo of the cycle of Aurelia aurita would be just great to explain the life cycle of scyphozoa that visit our zoo-aquarium. I thought maybe we could include this photo to our web fact sheet about moon jelly and to a text to educational text about jellyfish I am working on.
Do you agree us to use your photo for that educational purpose? Do you ask fees for that?
One more question. I wonder about they average size of the scyphistoma polyp of Aurelia aurita. Do you know about it?
