The unavoidable element of wildlife in Antartica is the penguins. It seemed that at every stop we made, those funny birds were there on the beach to welcome us to their towns. If they were troubled by our presence, they certainly didn't let on, as they continued to go about their business of gathering stones for their nests, caring for their eggs, or just standing there and observing.
While they are awkward on land, when swimming they are as graceful as any animal you've ever seen. They certainly seem far better adapted to the water than they are the land. While on the ship, I smiled every time I saw a group of them surfacing and briefly diving into the air, much like dolphins.
