“How do sea stars grip onto rocks?” That’s what listener Chloe wants to know. To find out, we take a trip to an aquarium to see sea stars’ tiny tube feet in action, and call up sea star expert Chris Mah. What we learn is a surprising story of how scientists made a big mistake when it came to studying to sea stars’ spectacular grip - and how they finally got it right. There’s some amazing science behind these starry creatures!
