The hammerhead relatives consume copious amounts of sea grass, and have the digestive machinery to process it—making them true omnivores. Christopher Intagliata reports.
Hawk moths hover while they feed, but they recover surprisingly quickly when knocked off-balance. Scientists use high-speed video and mini-cannons made of plastic toy parts to understand how hawk moths respond to disturbances midair.
