NPR today had a fascinating interview with wildlife photographer Paul Nicklen which was interesting just on the face of it, but became really intriguing when he began detailing his encounter with a leopard seal who was trying to teach him how to catch penguins! It's so sweet.
Here is this giant, lumbering seal who thinks Nicklen needs help catching dinner, so she keeps bringing him penguins (pictured) and wondering why he doesn't eat! The photograph is cool, but hearing him tell about the encounter is even cooler.
You can hear the interview, and see more of his photographs here.
