The animal kingdom and its false friends
An animal that looks like a fish can be a mammal; one that flies is not necessarily a bird. Our animal quizzes play with these misleading appearances, which catch out even keen documentary viewers.
Sorting like a scientist
Each sorting rule follows biology: family, way of reproducing or diet. Every species is explained at the end of the game, with a fact to help the right answer stick.
Frequently asked questions
How are animals classified?
Scientists group species according to how closely they are related, based on anatomy and now on DNA. The major groups (mammals, birds, reptiles, amphibians and fish) rest on features inherited from a common ancestor.
What is the largest animal in the world?
The blue whale, which can exceed 30 metres in length and 150 tonnes. It is the largest animal that has ever lived on Earth, dinosaurs included.
