Perfect for you if...

  • You want science writing that's genuinely funny without talking down to you, packed with real marine biology facts that sound made up.
  • You're curious about nature's strangest solutions to reproduction and don't mind the explicit details.
  • You care about ocean conservation but find most eco books preachy, so you'd rather learn through entertaining animal sex stories instead.

Maybe not for you if...

  • You prefer your ocean books serious and textbook-like, without jokes or anthropomorphic framing of animal behaviour.
  • You're looking for practical advice or self-help, not science curiosity for its own sake.
  • You'd rather not read extended passages about animal genitalia, no matter how scientifically interesting.

About this book

Marine biologist Marah J. Hardt explores the mating rituals of undersea creatures, from the elaborate courtship of armored lobsters to the synchronized breeding of groupers and the reproductive strategies of deep-sea squid, hermaphrodite sea slugs, and whales. The book examines the diverse and inventive ways marine life reproduces beneath the waves, including the anatomical adaptations of various species. Beyond documenting these reproductive behaviors, the book connects ocean sexuality to broader environmental concerns. Hardt discusses how overfishing, climate change, and pollution disrupt marine reproduction and the abundance of life in the sea, and explores how sustainable ocean practices can support successful breeding in marine ecosystems.
