Could you imagine having thousands of feet? With no brain or backbone, sea stars rely on a water vascular system and thousands of tiny tube feet to move, sense, feed, and cling tightly to rocks in the shifting intertidal zone. These sticky little feet are like hydraulic suction cups helping sea stars pry open prey like mussels and hold firm against crashing waves. The stars of this video are Ochre sea stars found along the Pacific coast of North America. They can be a deep purple colour to brigh

Most sea stars have five arms, and all have thousands of feet. They power themselves through a system of hydraulics, drawing water through narrow canals in their arms and pumping it out through said feet. They can move in any direction, either towards food, which they "smell" through sensors on the skin called chemoreceptors, or towards one another—biologists have observed them touching each other on purpose, perhaps to learn more. #oceanx 🎥: @Juliette Horn and Phillip and Patricia Frost Museum

Ever wonder how a sea star moves? By using tube feet! This sea star was seen cruising along the seafloor of Esmeralda Crater, an active submerged volcano that is part of the Vents Unit of the Marianas Trench Marine National Monument, during the 2016 Deepwater Exploration of the Marianas expedition. | NOAA Ocean Exploration
