Planning For Extreme Weather
Sea stars stranded at low tide can be exposed to brutal sunlight for hours. How do they beat the heat? Pisaster ochraceus regulates its body temperature by sucking up water during high tide, say scientists led by the University of South Carolina. And after a hot day, the sea stars take in even more water at the next opportunity. The cooling system lets sea stars stay closer to their preferred prey—mussels—which live higher on shore.
