About This Quiz

The animal kingdom is composed of millions of eukaryotic and prokaryotic organisms which come from many different species and habitats all across the world. From the ant which is smaller than a centimeter to the majestic blue whale which weighs almost 300, 000 pounds, they all play an important role in maintaining the ecosystem. Some animals have even evolved from a common ancestor, and although they look different and live in different habitats, they are distant relatives. 

Animals can be grouped in many different ways, from the class of animals to their feeding habits, to the place that they are found in and whether they are endangered or extinct. Some animals look nothing like each other but surprisingly share a few things, for example, the box jellyfish, the coastal taipan and the Brazilian wandering spider come from three different animal groupings but they are all some of the world's most poisonous animals. 

Which of these animals is not like the other? Will you be able to identify the odd one out of the group if you were given images of different animals? What will be the commonality between the others that makes the single animal different? There is only one way to find out, and that is by taking this quiz!
