Anna Claybourne is the author of numerous books on the natural world for young readers, including the Usborne Internet-Linked Encyclopedia of Planet Earth, Cheetah: Natural World Series, the Survival Skills Handbook, and many more.

She started her career at Usborne Publishing in 1993 as a trainee staff writer, and became a self-employed freelance writer and editor three years later. She writes on almost any subject but specializes in science and nature, and has written many children's books on wild animals (especially predators), volcanoes, earthquakes, and other natural disasters. Her interest in these topics made researching and writing 100 Most Dangerous Things on the Planet a particularly fascinating experience.
