The real question seems to be not whether animals can sense approaching earthquakes, but how. Still, that's only the first of several mysteries considered here. Why do elephants cluster around dead comrades--and do they sometimes bury their dead? Why do birds rub ants through their feathers, sunbathe on hot summer days, and, in the case of crows, "bathe" in fire? Could a chemical from hibernating animals put human patients or astronauts into the same state? How do migrating plovers know to head for Argentina? Why do groups of whales fatally strand themselves on beaches? How smart are dolphins? Curiosity-piquers all, with enough examples for lively reading, and enough facts and theories to launch further investigation.
