Hearing loud noises: Black rhino weighing more than 300lb tilted its belly up to the sky because it was too close to the newborn elephant

They are two giants of the animal kingdom, but that did not stop this male elephant and black rhino from clashing dramatically in a fearsome fight at a park in Africa.

Amateur photographer Louis Kok and his wife Marthie captured these extraordinary photographs of the large elephant attacking the female rhino – flipping it into its back and leaving it with its legs in the air.

The couple from Pretoria, South Africa, were photographing a rhino cow and her calf when the testosterone-fuelled, one-tusked elephant approached.

Protective mother: The rhino was attacked while trying to protect her calf from the rampaging elephant

The pair were stunned to watch the peaceful scene transform into a brutal battle as the bull elephant charged at the protective rhino mother.

Mr Kok said: ‘Male elephants on musth, fuelled by exorbitant levels of testosterone, are extremely dangerous, and will attack anything which stands in their path.’

Musth is a condition during which bull elephants experience a huge rise in reproductive hormones – testosterone levels can reach up to 60 times higher than normal – and this makes them extremely aggressive.

‘The elephant immediately toppled the rhino which landed helplessly on its back with its legs in the air,’ Mr Kok continued.

‘The elephant kept rolling the defenceless rhino around in the dust, while crushing it repeatedly under its enormous weight – in a traumatising display of speed, agility and brutal power.’

After the fight the rhino’s calf rushed to its injured mother’s side.

‘The calf remained in the vicinity for some time, circling her mother and attempting repeatedly to help her up,’ Mr Kok said.
