Happy Worm Week! Every episode this week will dig deep into the wonderful world of worms. Today's question comes from a listener who was wondering “What do worms do in the winter? Do they hibernate?” We asked biologist Andrew Gordus of Johns Hopkins University to help us find the answer.

Got a question that’s making you freeze up? Send it to us at BrainsOn.org/contact, and we’ll help wriggle out an answer.
