The stomach contents of Sphenomorphus variegatus from North Sulawesi not dependent to several sexual dimorphism variations; male and female investigated are opportunistic and widely foraging generalists. Analyses on the morphometric variations revealed that sexual dimorphism is significantly affected by intraspecific niche differences. The morphometrical differences of both sexes were significant at the length of radius (RL), humerus (HL), and tibia (TL) of each species. How the effect of the two locomotion limbs upon food habit will be discussed.
Key words : Sphenomorphus variegatus, morphometric variations, food habit, Sulawesi.
