Reaching for the weekend like a sea star. 🌟 Sea stars move with their tube feet. These hundreds of "feet" line the arms of the sea star and are part of the water vascular system. In addition to movement, tube feet are also involved in feeding and respiration. They operate through hydraulic pressure and secrete a sticky chemical to stick onto things like rocks, wharfs and tanks. This sea star may be reaching for the weekend, but it is more likely waiting for a snack (it's feeding day!). Those tu

Tube feet: Sometimes called podia, the sea star’s tube feet extend from the underside of each of the sea star’s rays. Tube feet can be visible from the aboral surface as they stretch out to move the sea star from one location to another. Tube feet aren’t only used for locomotion, they’re also used to hold onto food and pry clam shells and other mollusks open. The surface of the tube feet can exchange gases and nitrogen waste. | I Love The Ocean

Ever feel run off your feet? Sea stars certainly don’t—yet they move with surprising efficiency despite having no central brain. Their motion depends on the coordination of hundreds of tiny tube feet, each acting almost independently. This strange but effective strategy has fascinated researchers at the Kanso Bioinspired Motion Lab at the USC Viterbi School of Engineering, where scientists study how living systems move and apply those ideas to robotics. In a recent paper published in *PNAS*, the

The sea star uses hundreds of tiny tube feet to move. The tips of the feet form suction cups that grip any hard surface, allowing it to move up to 2 feet per minute. Clams and mussels are its meal of choice. Have you ever seen one move? #seastar #sealife #oceanlife #suctioncups #amazinganimals | Real Wild

Two feet? Meh. 15,000 tube feet? Now we’re talking. 🌟🦶 Tube feet are small suctioning tubes that echinoderms like sea stars and urchins use to cling onto surfaces, move, eat, and breathe. Sunflower sea stars—including the ones shown here at the Academy—have an absurd amount of these tubes clustered under their arms, earning them their genus name ‘Pycnopodia’ (“many feet” in Latin). Tube feet are also the reason sunflower stars can race across ocean floors at speeds of up to a meter per minute,
