The structural characteristics of the ventricular myocardium and the arterial distribution of the ventricular wall were studied in two freshwater teleost fish species (Piaractus mesopotamicus and Clarias gariepinus). The ventricular myocardium consists of two distinct layers, an external compact layer and an internal spongy layer. In Piaractus mesopotamicus the compact layer contains fibres with an external longitudinal arrangement and an internal circular arrangement. The arterial vascularization of the compact layer is provided by subepicardial vessels and their ramifications in both species.
对两种淡水硬骨鱼（美索不达米亚脂鲤和埃及胡子鲶）的心室心肌结构特征和心室壁的动脉分布进行了研究。心室心肌由两个不同的层组成，外层致密层和内层海绵层。在美索不达米亚脂鲤中，致密层包含外部纵向排列和内部环形排列的纤维。两种鱼的致密层的动脉血管化由心外膜下血管及其分支提供。
