There is more than one kind, but a very famous and delicious Italian mozzarella is Mozzarella Di Bufala, which is made from water buffalo milk. It has a tangy, rich flavour that is more interesting than regular cow's milk mozza, and it's very soft and melts almost liquid. I think this is the mozza you refer to.
However, many Italian cheeses are also made from good old cow's milk, including many mozzarellas.
Buffalo
The Water Buffalo's milk is used to make authentic Italian Mozzarella cheese.
