Anatomical structure which consists of a membranous sac used to temporarily store urine until it is excreted from the body.[AAO]
In tetrapods, the urinary bladder arises as an outpocketing of the cloaca. (...) The tetrapod urinary bladder appears first among amphibians and is present in Sphenodon, turtles, most lizards, ostriches among birds, and all mammals.[well established][VHOG]
The urinary bladder evolved in tetrapods. Birds to not possess a true urinary bladder, although Palaeognathae have an undifferentiated cloacal outpocketing that serves a similar function[https://github.com/obophenotype/uberon/issues/454]
