A female Komodo dragon relaxes with her mouth agape to intake water, letting the large volume trickle down her expansive throat. Females Komodos tend to be more cryptic than males, and this was one of only a handful we found on Komodo island. As she made her way to the watering hole the giant male turned his head to observe her, only to rest his head again in slumber.
