Here's a picture of a seal. Seals come from the sea into the area around Rothera. The most common seals here are Weddell Seals, like the on in the photo. These seals camouflage themselves against the grey rocks here very well, and I almost trod on this chap. These seals don't look particularly cute (to my mind) - they look like big fat slugs. There are some other seals here too, including Elephant Seals, Fur Seals and Leopard Seals. You can find out more about Weddell Seals here and here.
