The Surprising Story of Sea Stars' Sticky Feet

The Surprising Story of Sea Stars' Sticky Feet

“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.
