Here are some underwater images for Matt who would enjoy the challenge. The Seals were great fun as people were encouraged to move objects around to play with them. They are quicker in their movements than cats. The Four-Eyed Fish (Anableps anableps) have no swim bladders so tend to stay near the surface as they can't dive without using energy. The eyes are specially adapted to see above and below the water. The birds are Guillemot and Tufted Puffin.
