This week we talk about sex... in the sea! Anika Hazra speaks with marine biologist Marah Hardt about her new book "Sex in the Sea: Our Intimate Connection with Sex-Changing Fish, Romantic Lobsters, Kinky Squid, and Other Salty Erotica of the Deep". We discuss the multitude of bizarre strategies marine organisms use to get it on, the obstacles they face as humans become increasingly intrusive on their sex lives, and how we can protect the integrity of marine reproduction.
