Cloaca

Definition (http://en.wikipedia.org/wiki/Cloaca)

In zoological anatomy, a cloaca is the posterior opening that serves as the only opening for the intestinal, reproductive, and urinary tracts of certain animal species. All amphibians, birds, reptiles, and monotremes possess this orifice, from which they excrete both urine and feces, unlike most placental mammals, which possess two or three separate orifices for evacuation.
