摘要
猫头鹰的胃有一种特殊的功能,能将食物转换成半流质送往肠道,而皮毛、骨头、牙齿和羽毛等不能消化的部分则会留在胃中,被挤压成丸状并吐出。
The owl'stomach is unique.it convertsdigestible foodinto a semiliquid that goes into the intestine,while the undigested parts-such an fur,bones,teeth,and feathers-remain in tndare compacted into a pellet that is Iater regurgiated with a choking motion.
