1. Party penguins
Art fact: Eileen Agar, who took this photo at London Zoo, is an Argentine-born British artist. When she was young she travelled from Argentina to Britain with a cow and an orchestra, because her mum thought that milk and good music were needed for a happy life. She was the first female surrealist and experimented with new ways of making art and new materials.
Animal fact: To survive in such low temperatures, these penguins have special adaptations - they have large stores of insulating body fat and several layers of scale-like feathers that protect them from icy winds. They also huddle close together in large groups to keep themselves, and each other, warm.
