A helpless calf found itself at the centre of a dramatic stand-off between its herd and a pair of hungry lionesses.
This stunning series of photographs, taken in the Ruaha National Park in Tanzania, captures the moment the herd of elephants desperately tried to protect their calf.
Two herds of elephants had been drinking from the water, when the baby elephant appeared to become separated from the rest of the group as it tried to cross the Mwagusi River.
But two keen-eyed lionesses were quickly on the hunt, drawing ever closer to the terrified calf.

After making their first attack, the lions injured the calf. But the adult elephants heard is cries of distress and came rushing to the rescue.
Although they tried desperately to help the calf to safety, the baby was too badly injured and couldn’t walk.
After a tense war of wills between the two groups of animals, the lions eventually claimed victory and brought down the exhausted calf.
Tour operator Paul Tickner captured the dramatic scene on September 18.
The 30-year-old said: ‘There were two and then three lions on top of the elephant trying to bring her down.
‘Very quickly the elephant collapsed, seemingly from exhaustion, it looked like it was all over, but I knew the elephant was still alive.
‘The lions were anxious and kept looking around nervously as the calf screamed in alarm.
‘They had done this before and knew the noise could attract elephants nearby.’
Lions have been known to work together to kill fully-sized adult elephants but sightings of the kills are uncommon.
Mother elephants are known to be extremely protective of their young, but it is thought the baby calf’s parent was too far away to help.
