Army of Sea Cucumbers marching in Unison.
The website
LiveScience.com has a way of finding really cool pictures. The above picture of the
sea cucumbers was taken near the Larson B shelf in Antarctica.
The article doesn't explain their polarization, which is a shame because that's the most fascinating part. The same article had
this picture of a "psychedelic octopus" (
Paraledone turqueti).

And finally I'll leave you with
this picture--if you've got the stomach.
