[This haiku is based on a true experience. Every spring we watched the snapping turtle in our ornamental pond crawl up the hill, pick up an apple, and carry it back to the pond, where we could see it bobbing up and down as he ate it. Our question was always, How did he know when the apples were ripe and falling to the ground? Could he hear the thump of them hitting the ground? Vibrations? --quite a mystery.]
