S2E4 – The Queerness of Fish

Content Warning: This is a pretty wholesome episode. No fear, dear listener!

In honor of Pride Month, Rachel is taking us beneath the waves and beyond the binary into the fascinatingly queer world of fish! In this episode, she investigates stunningly fluid species that defy the concept of biological sex as an innate and immutable characteristic. SPOILER: Sex and gender in the animal kingdom is far from simple, guys. We should count ourselves lucky to live on such a beautifully un-boring planet. 🙂
