Disguises! (Halloween!)

What's a disguises? (How is it different from a costume?) Andrew & Polly solve a mystery for forlorn giraffes Kevin & Lousie, learn how to disguise their voices with voice actor Greg Chun, and explore the link between evolution and animal disguises (crypsis & camouflage) with CalAcademy's Rebecca Johnson! And as always, we ask our friends what they know about...DISGUISES! To learn more or to be on the show, visit earsnacks.org - thanks for listening!
