Yet more striking fluid/biomechanics.

Bat in wind tunnel from Carl Zimmer on Vimeo.

I'm posting this because it's amazing (and beautiful), shows fluid behavior, and to remind me, next time I want to whine about the challenges of our video work, that things could be much worse. I can't imagine how much work went into these high-speed videos of bats in flight.

And I really like bats.

The videos are collected and described here. They were created by two Brown University biologists, Dan Riskin and Sharon Swartz.

Thanks to Pharyngula for this find.

Update: More video at Sharon Swartz's site.
