About This Quiz

Animals are one of the first things you learn about as a child. We use them to learn the letters of the alphabet, and as a gateway to understanding the world around us. Animals are used to reflect personality characteristics, nations and political parties. You would think we know everything about animals.

Many of the things we thought we knew about animals have been proven wrong at some time or another. New species are discovered all the time, and in fact species evolve every day. In the London Tube, for example, there is a species of blood-sucking insect that feeds on the rats there and exists nowhere else in the world. At the same time, our understanding of the behavior of wolves has led us to reassess their social structure.

Were you paying attention in class when you were a child? Did you spend time reading the plaques at the zoo, or did you just look at the animals and move on? Are you able to name all the types of tigers or know what kinds of sharks are fearsome but harmless? Prepare your knowledge library, because now is the time to find out if you know which so-called facts are true and which are false! Take this quiz and find out!

Which of these dog facts is true?

There are many myths about dogs, mostly borne out of our close relationship to them. For example, while canine distemper can dry out a dog's nose, there are plenty of other health problems that do not express themselves through the state of the dog's nose. Similarly, there is a myth that dogs' mouths are cleaner than humans, because dogs use their tongues to groom themselves. This is terrible logic, and not true. Dogs have as many bacteria in their mouths as we do, and depending on their attitudes towards picking up random stuff outside, even more.

Which of these horse breeds is not real?
