Visiting scientist Guillermo Yudowski wants to make sea anemones happy.
Every morning, he arrives at his MBL laboratory and looks into a group of plastic tanks. Inside are samples of Aiptasia pallida, a hardy strain of anemone found in abundance near the University of Puerto Rico, where Yudowski conducts neurobiological research. Happy A. pallida, he says, are “colorful and open”; sad ones are closed and white. The white samples are near death and will only last three to four days in their containers.
