Abstract: In order to understand the difference in the biological indicators of Apodemus peninsulae and Apodemus agrarius, the two kinds of mice were dissected in the experiment, and the body length, ear length, foot length, tail length and carcass were analyzed.Weight, body weight, visceral weight were measured, compared and analyzed. The results showed that Apodemus peninsulae and Apodemus agrarius had extremely significant differences in body length, ear length, foot length, and tail length （P<0.01）; the heart weights of Apodemus peninsulae and Apodemus agrarius. The difference in spleen weight and lung weight was very significant （P<0.01）, kidney weight was significant （P<0.05）, and liver weight was not significant. The weight difference of Apodemus peninsulae and Apodemus agrarius was not significant, but the difference in body weight was significant （P<0.05）. The difference in body weight between ♀Apodemus peninsulae and ♀Apodemus agrarius was extremely significant （P<0.01）, and the difference in body weight is extremely significant （P<0.01）. ♂Apodemus peninsulae and ♂Apodemus agrarius had significant difference in stomach weight （P<0.05）, and ♀Apodemus peninsulae and ♀Apodemus agrarius had a significant difference in stomach weight （P<0.01）.
