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).
One may also ask, how do frogs eliminate waste? Frogs, like most amphibians, excrete solid and liquid waste through an orifice known as the cloaca. Liquid waste enters the cloaca for expulsion through the urinary bladder. Solid waste enters through the colon. The liquid waste excreted by a frog consists of water combined with ammonia, urea or uric acid.
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.
What are amphibians body covering?
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.
