Functional morpho-histology of the alimentary tract of the Indian Climbing perch, Anabas testudineus (BLOCH) has been described. The fish possesses a wide, slightly upturned mouth. The presence of jaw, vomerine, palatine, pharyngeal, and horny pad teeth in the bucco-pharyngeal region indicates the carnivorous feeding habit of the fish. Gill-rakers are toothed but the tongue is edentulous. The latter helps in manipulation of larger prey. The nature and disposition of the taste buds in the lips and bucco-pharyngeal region indicate that the fish procures its food primarily by taste and secondarily by sight. Taste buds are also present in the middle oesophagus which indicates that the gustatory sense extends upto this region. The surface epithelium of the cardiac stomach is conspicuous in having specific mucous cells. The pyloric stomach indicates a more primitive nature due to the presence of tubular mucous glands or pyloric glands. The number of pyloric caeca is 4. The intestine is slightly looped and the dimensionless RLG (Relative Length of the Gut) is 0.42. An ileo-rectal valve and the mucosal folds distinguish the rectum from the intestine.
印度攀鲈（Anabas testudineus，布洛赫）消化道的功能形态组织学已被描述。这种鱼有一张宽阔、微微上翘的嘴。口腔 - 咽部区域存在颌齿、犁骨齿、腭骨齿、咽齿和角质垫齿，表明其肉食性的摄食习性。鳃耙有齿，但舌头无齿。后者有助于操控较大的猎物。嘴唇和口腔 - 咽部区域味蕾的性质和分布表明，这种鱼主要通过味觉获取食物，其次是视觉。中食道也有味蕾，这表明味觉感知延伸到了这个区域。贲门胃的表面上皮有明显的特定黏液细胞。幽门胃由于存在管状黏液腺或幽门腺，显示出更原始的性质。幽门盲囊的数量为4个。肠道略有弯曲，无量纲的RLG（肠道相对长度）为0.42。回直肠瓣和黏膜褶皱将直肠与肠道区分开来。
