Sailing Blue
Beachgoers on the western coast of the United States in 2014 were confronted by several miles of squishy blue animals resembling jellyfish, but each was topped with a rigid structure like that of a sail. Each of these tiny organisms, titled “by-the-wind sailors,” measures about 7 centimeters (2.75 inches) long. Every so often, storm activity can bring them toward coastal regions, where they pile up on shores in large quantities.
