摘　　要：本文采用解剖学与组织学方法,研究了乌鳢脑各部分的组织结构,结果表明:乌鳢的脑包括端脑、间脑、中脑、小脑、延脑五个部分,各部分相互重叠;嗅叶和大脑构成端脑,且嗅叶不分化;端脑的体积与中脑的体积相当;小脑非常发达,但延脑不发达;由此可见,乌鳢是视觉和嗅觉较灵敏,善于游泳的凶猛鱼类,其脑部的形态特征与其生态学习性相适应。The study on the morphological and histological structure of the brain in Ophicephalus argus by the method of anatomy and histology. The results indicate that the Ophicephalus argus’s brain included five parts, the telencephalon, diencephalon, mesencephalon, cerebellum and medulla oblongata, and these five parts always overlap. The telencephalon consists of olfactory lode and cerebrum. The olfactory lode had no differentiation. The volume of telencephalon was almost the same with that of diencephalon. Cerebellum was very well-developed, but medulla oblongata was not well-developed. All above, the vision and smell of Ophicephalus argus were very sensitive. Ophicephalus argus was a fierce fishes being good at swimming. It’s showed that the morphological characteristics and eco-logical habits of Ophicephalus argus’s brain were coadapted.
