Cheryl (Lewis) Ames, a Research Assistant with the National Systematics Lab of NOAA’s Fisheries Service at the Smithsonian, has found that a tiny cubozoan medusa no bigger than a dime called Carybdea sivickisi has an intimate courtship routine. And she caught it in on film!
Its a little too spicy for us to share at the family-friendly Discovery Channel network, but if you go to the Smithsonian NMNH Department of Invertebrate Zoology website called "Jellyfish Romance" you can observe this intricate mating dance. Turn the lights down, sit back, and relax. Cue the music.

I like the cheesy music at the beginning of the video.
