General: cloaca
Images or animations depicting one or more characters who have a cloaca as part of their anatomical structure.
In many animals, including fish, reptiles, avians, dinosaurs and even a few mammals, the digestive, urinary and genital tracts open into a single common chamber called the cloaca. The term is commonly used to refer to the external opening of the orifice specifically, although this opening is more properly termed the "vent".
Not to be confused with genital_slit.
