On this special Valentine’s Day episode we talk to marine biologist Marah Hardt about 8-foot long whale penises, shark ejaculation systems, vagina mazes, fish orgies, and all the other crazy sex-stuff happening in our oceans. She’s the author of Sex in the Sea: Our Intimate Connection with Sex-Changing Fish, Romantic Lobsters, Kinky Squid, and Other Salty Erotica of the Deep.
