The morphology of scales from four flank regions in two species of Scorpaeniforme fishes of the family Platycephalidae was studied by applying light and scanning electron microscopy, and the age-dependent variability of scale structures was discussed. The scales of four flank regions from three size classes in both species were ctenoid. The posterior margin of all the ctenoid scales was formed by two rows of cteni, while the three complete rows of cteni were not observed in the examined scales. The cteni of both rows were similar in morphology. Some scale characteristics showed alteration during the fish growth, including the shape of the anterior region of scale in Platycephalus indicus, the presence of lepidonts in Grammoplites suppositus, and the general shape of scale as well as the indices SCL.SCW and JSW.SL in both species. Also, the number of cteni in posterior margin of scales was increased during fish development, while their general morphology did not change significantly. The number of cteni in the scales of small and large fishes in G. suppositus was found to be obviously lower than P. indicus. By considering the function of lepidonts in improving the hydrodynamic efficiency of swimming, it can be assumed that G. suppositus is not probably very active in swimming as P. indicus. As a conclusion, modification in the ornamentations of the posterior region are subject to alteration during the growth of the fish. Besides its developmental changes, some scale characters in the adult forms have taxonomic significance, including the square-shaped scales in P. indicus vs. the oval-shaped scale in G. suppositus; a total of 26–31 radii in the anterior field in P. indicus vs. 11–12 radii in G. suppositus; the presence of many (54–58) cteni in the posterior part in P. indicus vs. a moderate (19–23) cteni in G. suppositus. These characters could be used as additional morphological data to be used for studying systematics and even phylogeny of the flathead fishes.

应用光学和扫描电子显微镜研究了侧柏科的两种蝎形目鱼类的四个侧面区域的鳞片形态，并讨论了鳞片结构随年龄的变化。两种物种中来自三个大小类别的四个侧面区域的鳞片都是类胡萝卜素。所有类胡萝卜素鳞片的后缘由两排骨形成，而在检查的鳞片中未观察到三排完整的骨。这两行的形态在形态上相似。在鱼类生长过程中，某些鳞片特征显示出变化，包括印度侧柏的鳞片前部区域的形状，革兰氏栓中的鳞状鳞茎的存在。，以及两个物种的鳞片的一般形状以及指标SCL.SCW和JSW.SL。另外，在鱼类发育过程中，鳞片后缘的裂孔数增加，而它们的一般形态没有明显改变。发现假齿。（G. suppositus）小鱼和大鱼鳞上的切尼数明显低于印度假P（P. indicus）。通过考虑鳞翅目在提高游泳的水动力效率方面的功能，可以假定栓塞菌在印度象P. indicus那样可能不太活跃。。总之，在鱼的生长过程中，后部装饰的修饰会发生变化。除了其发展变化外，成年形式的一些尺度特征还具有分类学意义，包括印度对虾的方形鳞片与栓塞假单胞菌的椭圆形鳞片。总共26-31半径在前场在印度对虾与在11-12半径G. suppositus ; 许多（54-58）cteni的在后部分中存在在印度对虾与一个中度（19-23）在cteni G. suppositus。这些特征可以用作额外的形态学数据，用于研究the鱼的系统学甚至系统发育。
