Birds, insects, and reptiles living in dry habitats typically excrete uric acid. Uric acid can be excreted while the water in the urine is reabsorbed.
Penguins excrete through their anus
Nephridia!!!!!actually nephridia are the units that filter to make the waste, somewhat similar to our kidneys, the waste they excrete is urea, not ammonia (highly toxic, not good for its body to be surrounded by) and it isn't uric acid either which is usually made to conserve water--an earthworm surrounded in a moist environment doesn't need to conserve all that much water. Or poo.
no
Ants do not technically urinate, because they excrete all waste through a single orifice, which is called the anus.
No, bats excrete the same way humans do. Bat feces are called guano and are a valuable additive to fertilizer.
sodium chloride
Uriates
Yes
It is shorter in reptiles, they actually don't even have a loop of Henle. It is because when they evolved onto land, they needed to develop strategies to conserve water. The purpose of the loop of henle in mammals and other animals is to wash out the solutes out of our bodies, but reptiles need to conserve that water, so instead they have salt glands near the eyes and nose to secrete it. It also explains why they excrete uric acid rather than urea.
Yes. Like all birds, mammals, reptiles, amphibians etc., flamingos indeed excrete.
through urine
Urine
conserve sodium and excrete potassium
uric acid
All reptiles have a cloaca. which is basically their "vent" where they excrete waste, pee, mate and give birth from....
Both. They excrete solid uric acid, and defecate undigested fur from their food.
They excrete uric acid in paste form as their only excrement, but it is more expensive to produce as it is more complex molecule. So, sounds more like a trade off than a straight advantage to me. Now that I think about it, it does conserve water loss, which would be an advantage offsetting the cost of producing uric acid.
