There's no such thing as a Jellyfish

Just watch this in HD for the footage... It's beautiful!

"By all accounts, jellyfish are creatures that kill people, eat microbes, grow to tens of meters, filter phytoplankton, take over ecosystems, and live forever. Because of the immense diversity of gelatinous plankton, jelly-like creatures can individually have each of these properties. However this way of looking at them both overstates and underestimates their true diversity. Taxonomically, they are far more varied than a handful of exemplars that are used to represent jellyfish or especially the so-called "true" jellyfish. Ecologically, they are even more adaptable than one would expect by looking only at the conspicuous bloom forming families and species that draw most of the attention. In reality, the most abundant and diverse gelatinous groups in the ocean are not the ones that anyone ever sees." - YT

*promote awesome footage

Self promoting this video and sending it back into the queue for one more try; last queued Thursday, June 2nd, 2011 12:11am PDT - promote requested by original submitter Hybrid.

I'm not surprised there's no such thing as a jellyfish, because there's no such thing as a fish!

I thought jellyfish was a misnomer like starfish. Neither are "fish" and the preferred terminology now is sea jelly and sea star.

Great video. I think I'll play this in class next Spring. Thanks Hybrid!

That's because "fish" is polyphyletic - not a genetically distinct group. You could say the same thing about prokaryotes and reptiles.
