Unlike most other animals, frogs have mastered both land and water. Some of them are ridiculously poisonous; others have held the key to lifesaving medicines and treatments, including the world's first pregnancy tests and cures for skin cancer. They have been hailed as symbols of fertility and reviled as witches' familiars. Covering both familiar native British species and exotic rarities, this illustrated book celebrates these much-admired but often little-understood creatures. Latest in the sequence of wildlife books by Sally Coulthard.
