Question 3 transcript:
"One of the most interesting things is that some of the whales are easier to see underwater than with sound, than other whales. For instance, the muscular whales, like the blue whale and the humpback whale are relatively good reflectors of sound. So you can see them at a greater distance. But other whales, the ones that have a lot more blubber like the right whale, almost have an acoustic coating that keeps the sound from reflecting off of them and they're harder to see. So we detect them at a shorter range and we didn't expect that."
