Animal quizzes: sort the species

Mammals, birds, reptiles and insects: 4 free animal quizzes to sort species in under a minute.

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.

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.
