Terrestrials: A New Kids Show from Radiolab

Terrestrials: A New Kids Show from Radiolab

This is a serialised ongoing story, so jumping in at episode 10, for example, could confuse matters.

Listen to episode one here

In the depths of the ocean, a tiny male anglerfish catches a scent and follows it through the darkness. Eventually he finds a glowing, toothy female with a bacterial lightbulb on her head. He kisses her… and never lets go. Their bodies permanently fuse, merging bloodstreams, flesh, and digestive tracts.

Radiolab correspondent Molly Webster brings us the wild story of this eternal kiss. We dive deeper into glowing lures, bioluminescent bacteria, and the biology of two creatures becoming one.

Plus, Alan tells us about the time he broke a world record, and marine biologist Dr. Kory Evans answers our questions about some of the weirdest fish in the sea.

Big thanks to Molly Webster for bringing us this story. Check out all of her Radiolab stories, but if you want one to start off with, listen to Goo and You about butterflies!
