For grown-ups
Long-necked sauropods were the biggest land animals ever, some over 30 meters long. Scientists think several things helped: lots of plant food, air sacs that made their skeletons lighter, laying eggs rather than carrying babies, and long necks that let them feed widely without moving much. Being huge also protected them from predators.
