CATHERINE BARR studied Ecology at Leeds University and trained as a journalist. She worked at Greenpeace International for seven years as a wildlife and forestry campaigner and has a long-running interest in environmental issues. While working as an editor at the Natural History Museum, she researched and wrote two major summer exhibitions: Dinosaurs of the Gobi Desert and Myths and Monsters. Her previous books include 10 Reasons to Love a Turtle, 10 Reasons to Love an Elephant, The Story of Life and Elliot's Arctic Surprise. HANAKO CLULOW left Japan in 1997 for Ireland, where she studied visual arts and English. She then headed to England to explore her passion for child psychology, obtaining a BSc in psychology from the University of London in 2007. While she was deeply fascinated by child psychology, her passion for the arts re-emerged, which led her to pursue life as an illustrator. Her work draws upon a broad range of interests such as nature, the animal kingdom, psychology, fantasy and her native culture.
