The kidneys produce urine that is excreted from the body through the cloaca, an opening in amphibians used for the excretory, intestinal, and reproductive tracts. Nitrogenous wastes can be present as ammonia, urea, or uric acid. Arboreal species like tree frogs excrete uric acid to conserve limited water.
In respect to this, do amphibians excrete urea?
Amphibians, like most fish, excrete ammonia as the major metabolic waste (they secrete some wastes as urea when on land).
Beside this, what do reptiles excrete?
excretion. Excretion is performed mainly by two small kidneys. In diapsids, uric acid is the main nitrogenous waste product; turtles, like mammals, excrete mainly urea. Unlike the kidneys of mammals and birds, reptile kidneys are unable to produce liquid urine more concentrated than their body fluid.
Amphibians have smooth, slimy skin that is covered with mucus secretions. This keeps their skin moist and allows oxygen to pass into their bodies. Amphibians cannot drink water with their mouths. Water is absorbed through their skin.
