In a sight you certainly don't see every day, an antelope viciously attacked a giraffe, who had been resting at a zoo.
The fight took place at Rotterdam Zoo in the Netherlands on Tuesday (June 13).
Both of the animals have lived in the enclosure for years and are said to have had no problems previously.
A tourist filmed the incident which started out with the giraffe resting on its stomach, The Daily Star said.
The antelope then came up to the giraffe and whilst at first he seemed friendly, the animal suddenly started ramming its head into the giraffe.
Of course the giraffe stood up but rather than trying to fight, it seems to be running away, not that the antelope was having any of that.
The fight continued between the pair, whilst those watching screamed in surprise.
Other giraffes in the enclosure also quickly moved away as the antelope ran towards them.
