Then watched it again and noticed there was a digital credit noting Harvard University. Huh?
So I looked into it a little more and found this link for Lauder Laboratories at Harvard University that evidently studies fish locomotion in great detail. Part of this process is taking and analyzing HD video of fish movement, hence the odd YouTube snippets. Actually according to the website, they study "Kinematics & Hydrodynamics of Fish Locomotion" and "Fish Robotics, Biomimetics & Mechanical Design," but I'm sure you figured that out already.
So...fish robotics? I'm down, bring it on Harvard. Especially if it means the advancement of sharks with frickin' laser beams attached to their heads technology.
By the way, looks like they're getting closer!!!
