The shark shows us they're harmless to humans...mostly, but their excellent sense of smell helps them find other food sources to use their many rows of sharp teeth on. I'm a Fish is a series of animated short films which showcases sea creatures from all over the world - and under the water. It's quirky and it's fun! Each episode features a different fish, mollusc or crustacean who presents itself - quirks, tricks, fascinating design features and interesting facts about their habitat and how they survive in such deep, dark and sometimes dangerous places!
