The World's Smallest Species (c) Animals of all shapes, sizes and color make our wondrous planet what it is. Without true biodiversity the world would be a very different place as all animal species each play a vital role in ensuring and maintaining successful and habitable eco-systems.

Most people could answer simple quiz questions about what the biggest animal species are as blue whales, anacondas and ostriches easily spring to mind. However, what about the smallest animal species? Their tiny size often means that they are less well known than the animals that claim the giant titles but they play just as an important role in making up our world as we know it.
