No ,male dogs do not possess cloaca but placental mammals have cloaca in their embryonic stage.
In zoological anatomy, a cloaca is the posterior opening that serves as the only such opening for the intestinal, reproductive, and urinary tracts of certain animal species. The word comes from Latin, and means sewer. All birds, reptiles, and amphibians possess this orifice, from which they excrete both urine and feces, unlike placental mammals, which possess two separate orifices for evacuation.A cloaca is the posterior opening in birds, reptiles, fish and monotremes (egg-laying mammals) which is the single opening for the reproductive, intestinal and urinal tracts. These animals pass their urine, faeces and eggs as well as live young through this opening. The word actually means sewer.
No. Mammals do not have cloaca's.
Cloaca.
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.
Yes. A cloaca is present in marsupials and monotremes, as well as in birds, amhibians and reptiles. Placental mammals do not have a cloaca.
The urogenital system of the male frog is not much different than that of the female. In fact, the only difference is that the male will possess a pair of testicles, while the female will possess a pair of ovaries.
Cloaca - film - was created in 2003.
Monotremes, the echidna and platypus, have a cloaca. Monotreme means one hole, and is a reference to the cloaca.
Monotremes, which include just the echidna and platypus, have a cloaca.
Cloaca Maxima II was created in 1998.
No. All Mammals do not have cloaca's. The cloaca is a feature in only Birds, Fish, Reptiles and Amphibians which allows urine and faeces to pass through and hides the reprodeuctive organs. Mammals however have separate urine, reproductive and faeces tracks. Being the case, in male mammals, the urine and reproductive tracks are connected together and the faeces being only separate, while in female's, the tracks are all separated.
