With suggestive humor and a bit of orneriness, Cooke clears up crazy misconceptions about some of the world’s more mysterious and underappreciated species. Throughout, she dissects these past theories for signs of human superiority, a binary physical understanding, and a little too much of the woodsy musk from a beaver's “gonads.” What’s left: Hyenas are avid feminists, Eels keep their coitus quiet, and Sloths are pretty much the ultimate survivalists. You can devour this all at once or savor each chapter as an individual essay, but you will be amazed by the truth (and bestiary sketches) either way.
