For Halloween, we bring you an ode to three quintessentially creepy creatures (https://www.sciencefriday.com/segments/halloween-scary-animals-and-spooky-lakes/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) : bats, arachnids, and snakes. First, bat researcher Elena Tena joins Host Flora Lichtman to describe tracking the greater noctule bat in flight and learning that it can feed on migratory birds. Then, arachnologist Paula Cushing describes the camel spider, which is neither a camel nor a spider. And herpetologist Sara Ruane highlights one of her favorite snakes, the tiger keelback, which is both venomous and poisonous.  Plus, what makes a lake spooky? A pond possessed? Flora talks with Geo Rutherford, creator of the Spooky Lake Month (https://www.sciencefriday.com/segments/halloween-scary-animals-and-spooky-lakes/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri) series on TikTok and Instagram, to learn about some of the spookiest, most mysterious lakes on the planet.  Guests: Dr. Elena Tena is the national coordinator for the Spanish Bat Atlas project.
