| 摘 要： | 通过比较鳄蜥的体型与头部大小等特征的差异,研究了鳄蜥的两性异形情况.结果表明:性成熟鳄蜥个体体色差异显著,成年雄性头胸部腹面呈鲜红色或浅蓝色,而雌性为浅黄色或淡红色;成年雄性头部显著大于成年雌性(头长(HL),P＜0.001;头宽(HW),P＜0.001),成年雌性腹部长(AL)显著大干成年雄性(P=0.018);而成... |

| Abstract: | Through comparing the body size and head size among juveniles and female and male adults,the sexual dimorphism of Shinisaurus crocodilurus was studied. There was a significant difference in the ventral color of head and breast between the adults,i.e.,vivid red or light blue for the males,and light yellow or light red for the females. The head size (including head width (HW) and head length (HL)) of the males were significantly larger than those of the females (HL,P<0.001; HW,P<0.001),and the abdomen length ... |
