DR. TATIANA'S SEX ADVICE TO ALL CREATION

Those looking for prurient prose may be better off browsing their local adult bookstore, but readers intrigued by the bizarre facts surrounding animal whoopee (and really, who isn't?) should pay a visit to Dr. Tatiana, the alter ego of evolutionary biologist and journalist Judson. While her wryly salacious tone makes animal mating habits and evolutionary biology pretty racy, the book still reads more like a textbook than the Kama Sutra. Judson uses a tongue-in-cheek advice column format through much of the book, forging letters from dung flies, iguanas, sagebrush crickets and rodents ("Like, what's the deal? I'm a sleek young California mouse and am so in heat.") to explore reproductive biology. The device can be grating, and purists appalled by anthropomorphism may find themselves cringing as Judson chastises a male splendid fairy wren for philandering, while pronouncing his paddle crab counterpart a "gentleman." Still, Judson gets high marks for her copiously researched data. Perhaps most compelling is her chapter entitled "Aphrodisiacs, Love Potions, and Other Recipes From Cupid's Kitchen," in which the roots of animal homosexuality are examined. The reader will undoubtedly come away with reams of fascinating factoids, such as the nauseating dining habits of tropical cockroaches during copulation, and the pregnancies of the male seahorse and his cousin, the pipefish.
