The Mara River, snaking across the plains of East Africa.
As the land flattens out
rivers slow down and lose their destructive power.
Now they’re carrying heavy loads of sediment
that stains their waters brown.
Lines of wildebeest are on the march.
Each year, nearly two million animals migrate
across the Serengeti Plains
in search of fresh, green pastures.
For these thirsty herds,
the rivers are not only a vital source of drinking water
but also dangerous obstacles.
This is one of the largest concentrations of Nile crocodiles in Africa,
giants that grow over five metres long.
From memory, the crocodiles know the wildebeest are coming
and gather in anticipation.
The crocodile’s jaws snap tight like a steel trap.
0nce they have a hold, they never let go.
It took over an hour to drown this full-grown bull.
To surprise their prey
crocodiles must strike with lightning speed.
Here, only the narrowest line separates life from death.
