There are few animals more unusual than the echidna - a spiky, egg-laying mammal that eats ants. And the more we learn about them, the more intriguing they become. There's their multi-tasking snout, which they can use like a snorkel when swimming or to sense electromagnetic fields. They have strikingly complex brains, startling physical strength and 'backwards' back feet. And during the mating season, male echidnas will line up behind a female, cooing and forming an orderly echidna train, waiting for their chance to impress her with some truly remarkable reproductive equipment. In "The Enigmatic Echidna", Danielle Clode follows the echidna on its eclectic path through the Australian landscape. Equal parts surprising, amusing and enlightening, this is an irresistible journey into their unique and beautiful world.
