Both vagina and anus are anatomical terms with meaning beyond humans. Vaginas are found in all (female) placental and marsupial mammals. In fact, the only mammals that lack a vagina are the monotremes. The anus has the same distribution.
A Cloaca is a "common" urogenital opening, that is the primitive condition for vertebrates. That is, it's a single opening for the urinary system, the reproductive system, and the digestive system. A cloaca is found in all (?) vertebrates other than placental and marsupial mammals (Eutherians).

It is called the cloaca. It is most common in birds and reptiles. While researching this I found out that snakes actually have 2 penises, as do a lot of other lizards, with the notable exceptions of turtles, and the crocodilians. It didn't mention the komodo dragon, but I'm assuming it only has one. Not sure about pinipeds(seal, sea lions, etc.) or cetacaens(whales). I do know that a right whale has 4 ton testicles and ejaculates 500 gallons of sperm, and they gang bang a right whale cow that is in heat.

The term cloaca is from the Latin word meaning sewer.
It is the common cavity into which the intestinal, genital, and urinary tracts open in vertebrates such as fish, reptiles, birds, and some primitive mammals.

It is vagina or anus. Only in animals where the orifice is both the exit for the intestines and the genital opening is it called a kloaka. Birds, reptiles and amphibians have them, also monotremes (platypus).
