Their smaller size means they need less water to survive, and have slightly longer trunks to allow them to dig down into the sand to search for water underground. In fact, they only drink water every three or four days. Considering the elephants in Etosha National Park can drink up to 200 litres a day it just shows how they’ve had to adapt. When males reach puberty, they split off from their familial herd. There are two dominant bulls along this area of the river; Ollie and Arnold. The females travel in smaller groups than typical African elephants so as to ensure less pressure on finding food. They can travel up to 40/50 miles a day in search of water and food in such a sparse landscape. After watching Ollie for a short while we continued on.
