Morelet's tree frog
This frog lays eggs after heavy rain.  The female lays the eggs on rocks or plants that hang over the water.  The eggs are green in color.  When the tadpoles hatch, they fall into the water.  The eggs do not start to hatch for 9-12 days, and they take 2-3 days to hatch completely.  Most tadpoles hatch at night.  However, scientists have seen these eggs do something strange: If something shakes or disturbs the group of eggs—for example, a tree snake trying to eating some of them—the other eggs will hatch early.  This will also happen if the eggs fall into the water.
