Excretory Systems Excretion is performed mainly by two small kidneys. In crocodilians, snakes, lizards, and tuatara, uric acid is the main nitrogen-containing waste product. Unlike the kidneys of mammals and birds, reptile kidneys are unable to produce liquid urine that is more concentrated than their body fluids..
Besides, how do lizards excrete waste?
Aquatic reptiles tend to excrete a large proportion of these wastes as ammonia in aqueous solution. Terrestrial reptiles, such as most snakes and lizards, must conserve body water, and they convert their nitrogenous wastes to insoluble, harmless uric acid, which forms a more or less solid mass in the cloaca.
Additionally, what is the white stuff in lizard poop? The white chalky substance is the urates (pee). Lizards like to eke every last drop of water out of all they ingest so instead of peeing fluid they remove all the liquid until all that remains is the waste products of all they ingest. A whole lot more efficient than most mammals.
Thereof, do lizards poop and pee?
Lizards are common house pests, but they rarely cause problems at home. Lizard droppings can be easily identified because of its signature white tip, which is uric acid crystal from their urine. Lizards urinate and poop from one hole only called the “cloaca”.
Why do reptiles excrete uric acid?
Birds, reptiles, and most terrestrial arthropods, such as insects, are called uricothelic organisms because they convert toxic ammonia to uric acid or the closely-related compound guanine (guano), rather than urea. In this case, uric acid is excreted in urine instead of in feces, as is done in birds and reptiles.

To maintain their water balance, marine fishes drink large quantities of seawater, retaining most of the water and excreting the salt. Most nitrogenous waste in marine fishes appears to be secreted by the gills as ammonia. Marine fishes can excrete salt by clusters of special cells (chloride cells) in the gills.What color is lizard pee?
