Yes. A cloaca is present in marsupials and monotremes, as well as in birds, amhibians and reptiles. Placental mammals do not have a cloaca.
Yes. The platypus does have a cloaca. The cloaca is the external opening from the platypus's body, for both waste elimination and for reproduction.
Monotremes, which include just the echidna and platypus, have a cloaca.
The cloaca is the external opening from the platypus's body, for both waste elimination and for reproduction. The cloaca leads to the urinary, faecal and reproductive tracks, all of which join internally, and it is the orifice by which the female montreme lays her eggs.
The cloaca is the external opening from the platypus's body, for both waste elimination and for reproduction.The platypus is a monotreme. The term monotreme is derived from two Greek words meaning "one-holed", because they have just one opening, which is the cloaca. The cloaca leads to the urinary, faecal and reproductive tracks, all of which join internally, and it is the orifice by which the female montreme lays her eggs.
Monotremes, the echidna and platypus, have a cloaca. Monotreme means one hole, and is a reference to the cloaca.
Unlike most mammals, the platypus has a cloaca (one exit hole for waste and eggs). The platypus uses internal sexual reproduction (they use intercourse to deliver sperm to the female). The baby develops inside the female in an egg. The egg(s) are laid in a burrow.Another mammal with a cloaca is the echidna (It is also called the spiny anteater, but it is not at all related to other anteaters, it's just its nickname.)
No. Mammals do not have cloaca's.
Cloaca.
No ,male dogs do not possess cloaca but placental mammals have cloaca in their embryonic stage.
No, humans do not have a cloaca. A cloaca is a single multipurpose opening for the urinary, reproductive, and digestive systems found in some animals like birds and reptiles. Humans have separate openings for these systems.
A cloaca is an opening in the posterior of an animal. It is used to eliminate body waste such as urine. An inverted cloaca means that the cloaca is turned inside and is not opening properly.
Cloaca - film - was created in 2003.
A platypus is a mammal. Like other mammals, it feeds its young on mother's milk. It just so happens that it is a mammal which lays eggs. Therefore, it is a monotreme.Both platypuses and echidnas are monotremes. The name monotreme is derived from two Greek words meaning "one-holed", because they have just one external opening, the cloaca, for both waste elimination and for reproduction. The cloaca leads to the urinary, faecal and reproductive tracks, all of which join internally, and it is the orifice by which the female monotreme lays her eggs.
