Video Supplements

These videos contain supporting material for this study.

Files in this Data Supplement:

• Supplemental Video 1 - Ephyral Aurelia aurita (0.32 cm diameter) swimming through fluorescein dye. Original frame rate 250 fps, but only each 7th frame (.028 sec interval) is shown in playback. Time (sec) is shown in the upper right portion of screen. Note the stability of the dye mass relative to the ephyrae at the beginning of the video. Subsequently, the ephyrae swims into the dye and dye is retained between the lappets. Dye surrounding the ephyrae is shed during bell contraction as a series of dye “tracks” in the surrounding water. Video accompanies Figs. 6 and 7 in the text.
• Supplemental Video 2 - Subumbrellar flow of ephyral Aurelia aurita (0.29 cm diameter). Video was created by making 20 duplicates of each frame of a video taken at 60 frames per second; the total time represented in the video is 0.45 seconds. Note the transport of dye-marked fluid along the manubrium and into the subumbrellar space.
