摘　　要：对波纹唇鱼消化系统的解剖构造进行了研究,并利用扫描电镜对其肠道上皮组织进行观察,结果如下:波纹唇鱼为肉食性无胃鱼类,消化道全长极短,颌齿和咽齿都很发达,肠道极粗,比肠长为0.426;肝脏分三叶,呈枫叶状,胰脏弥散性分布在肝脏组织中,肉眼不易分辨;扫描电镜观察发现小肠前部细胞界限不明显,分泌孔较多,微绒毛密而长短不齐;小肠后部细胞界限也不明显,但分泌孔明显减少,微绒毛比小肠前部更密且很平整;直肠细胞为多角形,分泌孔比小肠少,微绒毛较稀疏,且长短不一。In this study,the digestive system of Cheilinus undulates Rüppell was dissected and observed. The epithelial tissue of intestinal tract was observed using scanning electron microscope （SEM）. The results are as follows： Cheilinus undulates Rüppell are predacity agastria fish; They have extremely short alimentary tracts and strong intestinal tracts; The ratio of intestine size to intestine length is 0.426; Jaw teeth and pharynx teeth are extreme upgrowth; Liver is divided into three parts,shaped like maple leaf; Pancreas is dispersed in liver tissue,hardly recognized by eyes. Cell boundary of anterior small intestine is unclear observed by SEM,many secretion pits are found,microvilli are dense but the length is uneven; Cell boundary of posterior small intestine is not distinctive either,but the number of secretion pits reduces obviously,and microvilli are denser and even; Recturn cells are polygonal cells,secretion pit number is smaller than small intestine,and microvilli are sparse and uneven.
