What do you recall when you say the animal kingdom? Maybe a lion gracefully sneaking savannah, perhaps a whale emerging from the blue ocean waves. Maybe a puppy curled up in your lap or an eagle circling over mountain peaks. Maybe a fox or a frog, a baboon or a bear, a cute turtle or a scary tiger. Nature is full of amazing creatures and we are lucky to share one planet with them. There are more than a million known animal species in the world, from the smallest breberk in muddy puddles to the respectable rulers of the jungle, and each of them is fascinating. However, some animals have something extra: they participate in groundbreaking discoveries, bring us important knowledge about the world, or even save human lives. Such is then indelibly written in history. This book was created in honor of the fifty of the most famous and reminding animals of all time and their remarkable lives. All fifty stories you read in it really happened. Some of them laugh at you, some make it to think, but all show how animals can be brave, intelligent and wonderful! Many heroes of our stories have done great things, and their merit is therefore worthy of our gratitude.
