The underwater world is home to some truly weird and wonderful creatures.
Species like the tropical clownfish make their homes among the deadly stinging tentacles of an anemone while others spend most of their lives inside the nooks and crannies of a coral reef - only venturing outside in search of food.
Although some fish are very brightly coloured, many are also very good at disguising themselves so make sure you take a really close look and don't miss anything!
