Happy Worm Week! Every episode this week will dig deep into the wonderful world of worms. Have you ever looked at an earthworm and wondered why some of them have a segment that looks like a tiny Band-Aid? Us, too! Luckily, biologist Andrew Gordus of Johns Hopkins University is here to help us find the answer.

Got a question that you’re wound-ering about? Send it to us at BrainsOn.org/contact, and we’ll help put a Band-Aid on your curiosity!
