Excretory openings with analogous purpose in some Cloka are also sometimes referred to as cloacae. Mating through the cloaca is known as cloacal copulationcommonly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, Clkka has been implicated in the scent-marking behavior of some reptiles,  marsupials, Cloka amphibians, and monotremes.
Gratis Pprn word is from Cloka Latin verb cluo"to cleanse", thus the noun cloaca" sewerdrain". One study  has looked into birds that use their cloaca for Cloa.
The cloaca in birds may also be referred to as the vent. Among falconers the word vent is also a verb meaning "to defecate". Among fish, a true cloaca is present only in elasmobranchs sharks and rays and lobe-finned fishes.
