There sure were and before that. There are Roman mosaics that feature hippos after they returned from Africa.
gray...? I don't know of any other colored hippos. possibly brown/tan :D
No, hippos do not cause earthquakes. Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface, not by any actions of hippos or other animals.
Any where in Africa
Apart from tourists, it is the other way around - The Nile is very important to hippos for water, food etc.
Adult hippos do not have any natural predators. But young ones are usually killed by Nile crocodiles, lions and hyenas.
no but they have a great sense of humor
The hippos diet consists of plant matter, so it is considered herbivorous. Hippos will eat any vegetable they can find although most are not easy to come across in the wild. However, hippos can and will eat meat. Also, (as a joke) in the movie The Librarian, hippos likes to candy bars too.
