Most snakes have a single opening called the cloaca through which they excrete waste lay eggs and copulate. The cloaca is located at the end of the snake’s body and terminates the digestive tract. The snake’s anus and the openings of the reproductive organs (ovipositor in females and hemipenes in males) empty into the cloaca.
In snakes the cloacal region may be partially divided by a septum (called the ventral cloacal septum in male snakes and the ventrolateral cloacal septum in female snakes) which separates the rectum from the urinogenital ducts. This septum is perforated in some species allowing the passage of urine and sperm from the cloaca.
The word “cloaca” is derived from the Latin word for sewer cloacae. The word “cloacal” is also used as an adjective to describe the anal and/or genital region of an animal.
Not all reptiles have a cloaca. Some such as the tuatara have a urogenital sinus which is a single opening that serves as the exit for the urinary and reproductive systems. Other reptiles such as lizards and most turtles and crocodilians have separate openings for the anus and the cloaca.
