As famous as the black cabs or red double-decker buses, the London Underground Map is loved for it's bright colours, striking design and unique style. When most people look at the 'tube' map, all they see is a pattern of colourful lines that helps them work out where they're going and how they're going to get there. But did you know that, hidden within the map, there is a world of Animals? The Animals were discovered by Paul Middlewick in 1988. They're created using the tube lines, stations and junctions of the London Underground map. Paul found the original animal, the elephant, while he was staring at the tube map during his daily journey home from work. Since then, Elephant & Castle, as the elephant is called, has been joined by many others from bats to bottlenose whales.
