Under the Sea

Here's a very cool video about undersea organisms by deep ocean explorer David Gallo. (A tip of the squid hat to David Thompson for the link.) The creatures he shows are really lovely -- and as anyone who's seen luminescent jellyfish at an aquarium or while diving knows, they're much prettier when seen with the naked eye.

The Gallo talk is part of a whole series of videos available at the TED Web site. All of them are interesting, and some are really excellent.
