Well, it depends. Males fight for dominance and the right to mate. Females get along great. Sometimes when a female brings her baby to her clan, one of the males will kill him so he doesn't have any more competition. So it really just depends
other hippos
well the male hippos enimes are humans and other hippos what he said ^
yes they do, in a group of 20-30 with one male
Hippos have no enemies, except maybe humans, other hippos and rarely crocodiles.
Hippos canines are used for fighting other males, and eating plants and grass.
Hippos don't hunt other animals. They are herbivores. Only very large crocodiles can kill adult hippos. Lion prides take on injured, old, or sick adult hippos. Young hippos are prey for lions and crocodiles.
gray...? I don't know of any other colored hippos. possibly brown/tan :D
They don't have to, they have no potential threats except other hippos but they still don't use camoflauge.
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.
they are just like dogs and are sick and act like they are fine afterwards
Hippos can eat fish because they are ominvores.
Hunting and other animals are killing them.
