uric acid
Birds, insects, and reptiles living in dry habitats commonly excrete uric acid as a waste product. Uric acid is less toxic and requires less water for excretion compared to other waste products like urea or ammonia. This feature helps these animals conserve water by minimizing the amount of water needed to flush out waste products from their bodies.
Reptiles excrete their nitrogen waste mainly in the form of uric acid, which is a less toxic and more water-conserving waste product compared to ammonia or urea. Uric acid is excreted along with feces in a semi-solid or solid form, minimizing water loss from the body. This adaptation is important for reptiles living in arid environments where water availability is limited.
Uric acid is primarily produced by birds, reptiles, and some terrestrial invertebrates, such as insects and arachnids. These animals excrete nitrogenous waste in a semi-solid form, which helps conserve water, making it advantageous for survival in arid environments. In addition, certain mammals, like the giant ground sloth, also produced uric acid, though most mammals primarily excrete urea.
Uric acid is a nitrogenous waste that requires the least amount of water to excrete because it is mostly insoluble in water. This makes it advantageous for animals in dry environments or those with limited access to water. Examples of animals that excrete uric acid include birds and reptiles.
They excrete faeces and uric acid from their cloaca.
No. Urea is generally excreted by MOST adult amphibians.
Birds, insects and reptiles conserve water by excreting uric acid. This is because the solubility of uric acid in water is poor thus can conserve water easily.
Reptiles and birds
Both. They excrete solid uric acid, and defecate undigested fur from their food.
