One of the great things about the animal world is the amazing diversity of the creatures that are all around us. There are reckoned to be around 8.7 million species of animals on Earth, with around 6.5 million land species, and 2.2 million animals in the oceans.
So, clearly, it is impossible to have a piece of animal wall art for each of them! It is however humbling to consider that even animals where you could maybe think of thirty or forty breeds (dogs for example) are actually far more numerous then you may realise (there are currently reckoned to be 340 breeds of dog).
Amazingly, while 8.7 million animal species may sound like a lot, the same study (by Census of Marine Life Scientists in 2011) estimates that 91% of all sea species and 86% of all land species have yet to be described, discovered and catalogued.
With many disappearing and becoming extinct before we even knew they existed.
