As I was reading my news feeds this morning, my attention was caught by this video:
Sea Urchins - Planktonic Origins from Parafilms on Vimeo.
Barely visible to the naked eye, sea urchin larvae grow and transform into bottom-dwelling urchins.
Plankton Chronicles Project by Christian Sardet, CNRS / Noe Sardet and Sharif Mirshak, Parafilms
See Plankton Chronicles interactive site: planktonchronicles.org
Watch the full video with related content here: http://www.richannel.org/the-plankton-chronicles--sea-urchins
This video is on a page from The Ri Channel "The Smart Place for Science". The Sea Urchin video is part of the Plankton Chronicles, every one of which is as weird and wonderful as the Sea Urchin story. (The plankton videos are also housed at Vimeo, by their producer.)
