Here at Moment of Um, we love fishing for questions, and the one we’re answering now is a great catch. It comes from Marc, in Miami Florida: When lakes form, how do fish get in them? Associate Professor Megan McPhee from the University of Alaska Fairbanks helps us get to the bottom of this topic. If you have a Moment of Um question, send it to us at BrainsOn.org/contact and you could hear the answer on a future episode!
