SEXUAL DIMORPHISM IN HEAD AND BODY SIZE IN THE SKINK, EUMECES CHINENSIS

The data on sexual dimorphism in head and body size in the skink E. chinensis are reported in this paper. The adult males in the sample had slightly greater snout-vent length and body mass than the adult females. No signficant differences were found in relative head length. relative head width. and relative head height between subadult males and females. The adult males had significantly greater relative head length. relative head width, and relative head height than the adult females and subadults. No significant differences were found in relative head length. relative head width. and relative head height between subadults and adult females. Males. after sexual maturity. bud a faster bend growth rate than females.
