Brittle stars are the more flexible cousins of sea stars. While sea stars move slowly across the seafloor on tiny feet, brittle stars whip their long arms around to swim, climb corals, and catch food drifting in the currents. When threatened, they can completely detach their arms to escape predators. Their arms are the "brains" of the operation. The arms are home to bundles of nerves that allow the brittle star to coordinate complex movements, without a central processing center. Brittle stars h

Do wishes still work if you make them on a shooting sea ⭐? Sea stars move using their water vascular system, a network of canals and tubes running through their body, similar to our veins and arteries. Water enters through an opening called the madreporite, or "mother pore", and flows all the the way to the small tube feet found along the bottom of each arm. By redirecting the water, sea stars can extend or retract the tube feet, move their arms, or even pry open the shells of clams and mussels!

How do starfish move with hundreds of legs but no brain? 🤔 The marine invertebrates, also known as sea stars, lift their bodies off the ground with their tiny tubular feet to move across underwater surfaces. Their feet are coordinated purely through mechanical loading, enabling the animals to bounce rhythmically along the seabed without a central nervous system. This new understanding of how they manage this could inspire underwater exploration robots that work on the same principles. https://w

Researchers thought sea stars simply crawled along the sea bottom—but new research found that at least five species of these creatures bounce when startled or hungry, suggesting this behavior is widespread: https://fcld.ly/y12qnk0 | Science

Ever wonder how Sea Stars move around? 😮 Most people know Sea Stars to have 5 arms; however, some species can have up to 40! Each arm has hundreds of tiny tube feet that are used for locomotion, respiration, and catching their prey. Sea Stars don’t have blood or circulatory systems. Instead, they have a water vascular system which allows them to use hydraulic pressure and suction to move their tube feet. Check out these Sea Stars in our Tidepool Touch Tank located in our Rivers to the Sea exhib
