The microscopic world of corals [video]

[Video Link] Here's an amazing video from PBS Digital Studios' “Under H2O” series, with micro images of corals.

Corals are beautiful when seen through your own eyes in sunlight, but for scientists at the University of Hawaii, seeing corals in this manner is not enough. They are using a revolutionary new tool called a laser scanning confocal microscope to take photographs of corals that are one part art and one part science. In this episode, they take us along for a ride with this amazing new technology and show us corals in a way we have never seen them before.

Short film about Intertidal ocean life

PBS Digital Studios has launched a biweekly series called Under H2O, and the first episode is called "The Intertidal." It's only five minutes long, and well worth watching.

‘The Intertidal’ features rare underwater footage of a part of the marine world that often goes unexplored by scientists and cameramen alike: the intertidal. In this episode, Dr. Musburger and his team take cameras underwater as they sneak into this largely unexplored habitat during the short window of time when the tide is out and tide pools are accessible. With unmatched wave energy, temperature fluctuations, and salinity changes, only the hardiest plans and animals survive.

Hagfish ties itself in a knot

Apparently, October 19 was Hagfish Day. I nearly missed it. But please enjoy this video and celebrate for the next hour. Also recommended: This song about hagfish.
