This is the dramatic moment a pair of sparring impalas are ambushed by a lioness with deadly consequences.
The impala makes a desperate attempt to flee, but is ruthlessly taken down by the lionness, which sinks its teeth into its prey.
Augustine, from Gold Coast, Australia, captured the stunning footage during a holiday to the Masaai Mara Conservancy in Kenya late last year.
