The World’s Deadliest Hunters, Past and Present

The Siberian tiger, the great white shark, and many other present-day apex predators are powerful and deadly. But in the past there were even more lethal killers — animals that stalked their prey thousands or millions of years ago.

Do all the insects in the world weigh more than all the humans?

Which animal can survive both boiling water and the vacuum of space?

Which animal sleeps more, a python or a bat?

Which animal is more dangerous: a shark or a hippopotamus?

These questions and many more are answered in Animals by the Numbers. Mind-boggling facts, figures, and comparisons are explained with colorful, easy-to-understand infographics and illustrations.

This book is filled with unexpected and accessible information.
