From the transcript:
"Thanks to a couple of engineers at MIT, we were able to use a prototype camera called the Edgertronic to capture slow-motion video... And that particular camera gives us an insight into what fairly common animals do but we can't even see it in the blink of an eye. ... It gives us an insight into some of the animals that we were sitting right next to for 31 days and never normally would have paid attention to, such as hermit crabs."
"Using a cutting-edge piece of technology that's not really meant for the oceans is not always easy. We sometimes had to put the camera upside down, cordon it back to the lab, and actually man the trigger from the lab itself. But what this gives us is the foresight to look at and analyze in scientific and engineering terms some of the most amazing behavior that the human eye just can't pick up, such as this manta shrimp trying to catch its prey, within about .3 seconds. That punch is as strong as a .22 caliber bullet, and if you ever try to catch a bullet in mid-flight with your eye, impossible. But now we can see things such as these Christmas tree worms pulling in and fanning out in a way that the eye just can't capture, or in this case, a fish throwing up grains of sand. This is an actual sailfin goby, and if you look at it in real time, it actually doesn't even show its fanning motion because it's so quick."
