Mammals.

Being the biggest fish in the world seems like it would help the whale shark survive. However, its size actually makes it slow and easy to attack. Similarly, giraffes’ height allows them to grab food other animals can’t, but it makes drinking from a pool on the ground very awkward! Readers find out many more cases of extreme animal adaptions and their drawbacks. Fact boxes accompany full-color photographs of each animal, describing the animal’s most interesting physical features as well as their range, size, and lifespan.

Books in the Extreme Animals series reveal examples of some of the most bizarre, amazing, and extreme animals in the world. This book looks at marvellous mammals, including prickly porcupines, poisonous platypuses, and terrible tigers.
