What if you didn’t send food down to your stomach to digest it, but you sent your stomach up to your food instead? This is exactly what the sunflower seastar does. With 16 to 24 arms and 15,000 tube feet to help grab, open and eat clams, snails, abalone, sea cucumbers, and sea urchins.
The sunflower star is the largest sea star in the world. It’s also one of the fastest animals on the ocean bottom, crawling one metre… a minute, which may not seem that fast to us but is speedy if you’re a clam just chillin’ on the sand.
