| Abstract: | We measured some morphological traits, including the body length, head length, length of proboscis, diameter of eye, eyes interval, head length behind the eyes, and head height of Pseudobagrus fulvidraco. Female body is notably shorter than male body. The head length, length of proboscis, diameter of eye, eyes interval, head length behind the eyes of male and female individuals grow at the same speed at which the body length grows, with no remarkable difference. Female individual's diameter of eye and head height grow at a remarkably greater speed than male individuals. |
