Animals
of all shapes, sizes and colour 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.
