The Hippopotamus is a species of large mammal from the present day, in Africa. It weighs up to 4 tons, in the largest specimens, and can grow more than 10 feet long. It is semiaquatic and is so adapted to its underwater lifestyle, that it can remain underwater with only the tips of its ears, eyes and nose, sticking out above the water's surface.
At a South African safari park, Danny Quinn and James Lester witnessed several hippopotamus fighting with a Eustreptospondylus. However, they all scattered, when a much more dangerous Postosuchus arrived at the watering hole and began fighting with the Dinosaur. (Fire And Water).
- The Hippopotamus was one of only two species of present-day animals to battle a creature from prehistory (the other being lions, whom also appeared in Fire And Water).
