In their study, indicated that E- coloratus selects the most suitable place providing it as much possible of physical energy while waiting its pray, also indicated in his study that there is a strong correlation between body temperature and soil and air temperatures, and this is consistent with the results reported in this study indicating a significant positive correlation between E- Pyranidum body temperature and soil air temperatures both in summer and winter; and this may be a reliable explination in the variation of daily activity for E- Pyranidum snake according to seasons.
