This one doesn't end the way you'd expect. Inspired by the Netflix documentary series "Night On Earth," we learn everything we can about a mouse and scorpion who do battle on the regular — from two scientists who study them: Ashlee Rowe at the University of Oklahoma and Lauren Esposito at the California Academy of Sciences. If you have Netflix, you can watch the critters clash about 18 minutes into the episode 'Moonlit Plains' here.

And you can learn more about grasshopper mouse vocalizations from Northern Arizona University's Bret Pasch here.Email the show at shortwave@npr.org.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
