title: Ecology of the Sand Boa, Eryx jayakari in Riyadh Region of Saudi Arabia.
abstract: The ecology, feeding habits and sexual dimorphism in Arabian Sand Boa, Eryx jayakari from the Central region of Saudi Arabia, were studied. In this study the E. jayakari was recorded for the first time from several sites. Significant differences were noted in total length of body and tail, and body diameter of male and female. The females were of larger size. The mean number of the dorsal body scales, ventrals and subcaudal for both sexes were not significantly different. The mean number of the dorsal body scales, ventral body scales and subcaudal scales for the females was 43, 169 and 18 scales which were not significantly different from respectively ones in males 42, 168 and 18 scales. Frequent prey consumed were lizards (50%), rodents (25%) and arthropods (12.5%).
