A marine biologist’s “funny and entertaining” look at the mating rituals of undersea creatures (Miami Herald). Forget the Kama Sutra. When it comes to inventive sex acts, just look to the sea. There we find the elaborate mating rituals of armored lobsters; giant right whales engaging in a lively threesome while holding their breath; full moon sex parties of groupers and daily mating blitzes by blue-headed wrasse. Deep-sea squid perform inverted 69s, while hermaphrodite sea slugs link up in giant sex loops. From doubly endowed sharks to the maze-like vaginas of some whales, Sex in the Sea is a journey unlike any other to explore the staggering ways life begets life beneath the waves. Beyond a deliciously voyeuristic excursion, the book also connects the timeless topic of sex with the timely issue of sustainable oceans—revealing how overfishing, climate change, and pollution are disrupting the creative procreation that drives the wild abundance of life in the sea, and how we can promote successful sex in the sea. “Hardt’s writing is often spectacular at describing the rituals and courtships of underwater reproduction.” —The New Republic “Weird [and] excellent.” —GQ “An oceanographic Kinsey Report.” —O, The Oprah Magazine “[Readers] will find much to learn in this well-written and delightful study.” —Library Journal (starred review)
