摘　　要：对中国海洋大学鱼类标本室保存的部分鲈形目鱼类——鲷科 Sparidae,大眼鲷科 Priacan-thidae,科 Serranidae的几种鱼类的口腔齿进行了研究。结果显示 :科与大眼鲷科的前颌骨、齿骨、犁骨、腭骨、咽骨上都着生有形态较单一的口腔齿 ,但较小 ,不是很坚固 ;而鲷科的几种鱼类口腔齿都着生在前颌骨、齿骨、咽骨上 ,且较强硬 ,形态较多样 ,特别发达。本研究为 3种鱼类的进化关系提供了某些佐证。This paper studies the oral-cavity teeth of several perciform fishes, Pagrosomus major (Temminck & Schlegel), Sparus macrocephalus (Basilewsky), Taius tumifrons (Temminck & Schlegel), Parargyrops edita Tanaka belonging to sparid fishes, Priacanthus tayenus Richardson and ,Pricanthus boops (Bloch et Schneider) of the family Priacanthidae , Siniperca scherzeri Steindachner and Lateolabrax japonicus (Cuvier et Valenciennes) of the family Serranidae in morphology and ecology, comparatively. It reveals that the sparid fishes have premaxillary teeth, teeth in lower jaws, pharyngobranchial teeth and pharyngeal teeth. They are sharper, keener and bigger. In compared with these, the others have vomerine teeth, palatine teeth, in addition to the types of teeth of sparid fishes. And these (vomerine teeth and palatine teeth) are all smaller and are villiform teeth. These eight fishes are different in their habitats, feeding habits and other respects of ecology. In fact, feeding is a well-known factor that influences head morphology, including the morphology of oral-cavity teeth. Because of long-term evolution, adaptation to the environment and natural selection, their morphology of oval-cavity teeth has differentiated. Then their niches are very different in the ecosystem.
