摘要
对蛇雕消化系统进行了解剖观察 ,结果表明 :蛇雕有锋利的喙 ,利于撕裂食物 ;舌根表面具有尖端指向后方的栉状突 ,可防止食物滑脱 ;粗大且收缩性较大的食管 ,嗉囊发达 ,肌胃不太发达 ,相对于体长而言肠管较短 ,但小肠较发达 ,具有不发达的双侧盲肠。并与部分食植物的鸟类作了比较。
The morphological constructure of digestive system of Spilornis cheela has been observed by naked eyes and under dissecting microscope. The results show that there are many bomblike papillas pointing towards hind section in roof of tongue;the papillas at the end of two branches of tongue root become stick like;these papillas can prevent the escaping of food;it has developed crop;it has sharp beaks for lacerating the food;and the small intestine is very much developed but cecum is very degenerate. According to the comparison between Spilornis cheela and some other birds,the carnivorous birds have very developed small intestine and undeveloped cecum,but herbivorous birds have mild developed small intestine and very developed cecum.
