Did you know there are 18 species of penguin in the world? Each species has its own differences and quirks, but one thing all penguins have in common is that it can be tricky to tell if they’re standing up or sitting down. One curious listener wondered if they even sit down at all. We asked Dr. Michelle LaRue from the University of Canterbury to help us find the answer.
