In comparison to many other species, hippos have been the subject of little formal research.  Much of what we know about hippos comes from research performed during mass culling programs in Uganda in the late 1950's and early 1960's.  However, more recent discoveries, some of which have occurred quite unexpectedly, have researchers taking a new look at both common and pygmy hippos.
