Popular Science explains:
Whale snot, it turns out, is packed with DNA, viruses, hormones, and microbes—all incredibly useful things to a variety of scientists.
Typically, marine biologists employ the same techniques that failed Kerr: A motorboat equipped with long sticks and modified crossbows to collect whale biopsies. But Kerr hopes these flying research robots will soon change that.
