Source: www.telegraph.co.ukA gecko licks the morning dew off its eyeballs. This gecko is found on coastal sand dunes in Namibia. The nocturnal reptiles collect water on their eyeballs in the early morning when a mist bank descends as cool coastal air hits warm desert air. Then they lick it off to have a drink. It took photographer Isak Pretorius three days in to get the licking picture, following gecko tracks across the dunes through the mist.
