As this video shows, scallops are a lot more agile than they look. In a snap, they catch prey, and fend off much larger (and hungry) sea stars. But, now, we know they also can cough. And that coughing can offer clues to the health of the water it lives in, but in the opposite way that we cough. Scallops cough to expel feces and water; if the water’s polluted, they feed less, and may not cough out as much. A French-Scottish research team found that listening to this coughing could help determine water health, using scallops at a distance.
