| 摘 要： | 本文对硬骨类中的5个目、8科、8属、8种鱼类的消化系统作了比较解剖研究。8种鱼类均为肉食性，但由于所摄取的动物种类不同，因此8种鱼类在消化系统各部分形态结构上各具特点。消化系统各部特点是与食性及食物种类相适的。

| Abstract: | This paper deals with the comparative anatomy of the digestive system of eight species of marine fishes belonging to five orders, eight families and eight genera.The eight species mainly feed on fishes, crustaceanes, mulluscses and so on.Their mouths are all smaller, with small or degenerated teeth, their stomaches show three varieties of pattern (i, e., l, U, and Y pattern). The eight species of fishes are all carnivores. Their stomaches and intestines obviously become divided.The small intestines of the eight species are all shorter. All the fishes, except Fugu Xanthopterus, possess pyloric caeca (ranging from 4 to over 600). |
