"We nicknamed this one "Can Opener." The first thing we do, when an animal dives, is to go to the location to get samples. A whale would dive, and we’d go to the flukeprint, the calm print of water it makes when it dives. Can Opener would hide, underwwater, and the second the boat would get there, it would make a huge bubble cloud, then come up and circle the boat two or three times and then dive for real. Those behaviors, seen once, are just weird … but that individual is known for doing all sorts of stuff around the boat, playing with our hydrophones and whatever. These animals are individuals."
