Can horse bite?

News this morning shows that horse actually can bite. A boy in Penang was bitten by a horse during an exhibition when he was climbing down from the horse ridden.

Strangely enough this is my first time hearing such news. I remember went to Bkt Cahaya last month with friends and actually horse's teeth are not sharp, and moreover horses should be smooth type animals. We've heard a lot about dogs biting passer-by, pedastrians, tigers or lions biting people, but how on earth can a horse bite? This remind me of the movie "Black Sheep" where sheep can kill after being cloned.

Hope this is just a one off incident and no more such news appear, otherwise we, human beings shall start worrying since we do not know which animals going to attack human.
