Question

Which of the following animals have a cloaca?
A. Psittacula
B. Gallus gallus
C. Pavo cristatus
D. All of the above

Answer 1

Hint: The cloaca is the single posterior opening for the bird's digestive, urinary, and reproductive tracts and is used to expel feces and also lay eggs. It is found on the rear of the body under the base of the tail, covered by the feathers on the extreme lower abdomen.

Complete answer: Cloaca is the posterior opening which serves as the one and only opening for the digestive, reproductive, and urinary tracts in many of the vertebrate animals. All of the amphibians, the birds, the reptiles, and also a few of the mammals have a cloaca from which they excrete both the urine and the feces.
-The Psittacula is a genus of parrots. They are the ring-necked parakeets as they are commonly known in the aviculture origins found from Africa to South-East Asia.
-The Gallus gallus is the red junglefowl which means the wild chicken. It is a tropical bird in the family Phasianidae.
 It ranges across much of Southeast Asia and parts of South Asia.
-The Pavo cristatus is the blue peafowl or peacock.
Therefore, the correct answer is option D.

Note: A cloaca is an orifice through which the urine and the feces are eliminated in the birds, the reptiles, the amphibians, and also in a few of the branches of the mammal family tree. It also serves a reproductive function like the vagina in the females of these species and also performs the function of sperm ejaculation in males in some of some species.
