This video was given to me by Chef Vova at the Ukrainian station, Vernadsky. I'm not sure exactly when it was taken, or who took it, but it was in the waters around their base.
Penguins aren't really afraid of people. During the summer here, you can walk through flocks of them, and sometimes they barely even acknowledge your presence. They've only had contact with humans for the past couple hundred years, not enough for them to instinctively fear us as predators. And now, they're a protected animal, so they've got nothing to fear from us.
Killer Whales, on the other hand, see penguins as lunch.
