Amphibians have mesonephric kidneys that cannot concentrated urine above plasma osmolality. A single or bilobed urinary bladder is present in most species. Larvae and aquatic species are primarily ammoniotelic while terrestrial species are primarily ureotelic. There is a lesser number of primary uricotelic species (waxy tree frogs). Clawed frogs have the ability to be ammoniotelic or ureotelic depending on water availability.
