Moon Jelly Strobilation Display

Jellies live their lives in two body forms or stages. There is a polyp or attached stage which resembles tiny sea anemones (jellies and anemones are actually related) and a medusa or free-swimming stage. The trick to getting jellies to go through their life cycle (both stages) is to get the attached polyps to begin to strobilate, or bud off new juvenile jellies. This may sound simple enough, but the polyps are very comfortable just staying as polyps. You actually have to “trick” them into budding by changing some of their environmental conditions such as temperature, water chemistry and/or nutritional factors.

Head Curator Lisa Scott (class of 2007) designed and built a Moon Jelly Strobilation display for her Senior Project. She was able to successfully strobilate jellies which will ensure that we have a steady supply of adult jellies for our popular kreisel, or jelly display.

So next time you stop by the Aquarium make sure to check out Lisa Scott’s juvenile jellies in the new Moon Jelly Strobilation Display.
