Unlike the kidneys of mammals and birds, reptile kidneys are unable to produce liquid urine more concentrated than their body fluid. Many birds and reptiles inhabit areas close to the sea and, as a result, they ingest large quantities of salt. "Soft-shelled turtles are often found in brackish water or even the sea," Ip told LiveScience.Peeing requires drinking freshwater to wash out urea, but saltwater is not safe to drink. The excretion process also serves to normalize water and ions in the body. © 2020 Leaf Group Ltd. / Leaf Group Lifestyle The kidneys serve to filter the nitrogen from the animal's bloodstream, then turn it into waste. Turtle docks, ramps, and floating platforms work well for smaller specimens, but large females will need a sturdier basking spot. Surprisingly, the researchers discovered the water the turtles were kept in held more than 15 times the urea that was in their urine.The scientists then kept the turtles in dry boxes and gave them a puddle they could dip their heads into.
The nitrogen then exits the body in dry form as uric acid crystals along with the feces.
Some of the nitrogen is used by the body, but the majority must be excreted as a waste product.According to the University of Cincinnati, the main way that both birds and reptiles rid their bodies of the surplus of nitrogen is by turning nitrogen into uric acid or ammonia.
This still leaves them facing net water loss and ion gain. The bodies of these animals excrete the excess salt in the form of a salt solution through nasal salt glands.According to New World Encyclopedia, reptiles use two small kidneys as tools for excretion.
Both species are able to efficiently remove the nitrogen while losing very little water in the waste product.The excretory system of birds and reptiles effectively removes nitrogen from their bodies, and this system allows for the preservation of water. Future US, Inc. 11 West 42nd Street, 15th Floor, According to Back Yard Nature, when mammals excrete nitrogen, it is the form of urea, which dissolves very easily in water. NY 10036.
According to Stanford University, the kidneys in a bird also function as a means to remove nitrogen from the blood. The excretion process also serves to normalize water and ions in the body.
How do octopuses do it?
New York,
Filtration Sliders are messy feeders and produce a lot of waste.
How Do Octopuses Poo? This is because they lack a specialized structure present in the nephrons of birds and mammals, called a Loop of Henle. The excretory system exists in all living creatures in order to facilitate the removal of nitrogen rich minerals, as well as additional waste products.
In both reptiles and birds, eliminating the nitrogen requires that the body exerts a great deal of energy.
For the deposit the corresponding figures are: ammonia, 6.0%; uric acid, 88.6%; urea absent. As food is ingested, the bodies of each of these species begin to undergo the metabolic process. Some fish excrete urea, the main waste product found in urine, out their gills. Why share?
In the present study both the liquid and the deposit have been analysed. For the liquid urine, the following values for percentage of total nitrogen have been found: ammonia, 66.8%; urea, 12.5%; uric acid, 2.3%. According to the University of Cincinnati, metabolism serves as a means to break down protein and nucleic acid, both of which contain nitrogen.
Do red eared slider turtles eat their own poop?
The white substance found in bird droppings is actually uric acid, which is not water soluble. The researchers speculated these turtles might excrete urea out their mouths when they dunk their heads into water, seeing as the reptiles possess strange gill-like projections there. 1. "Contrary to this common notion, our results suggest that the mouth can be a major route of urea excretion in soft-shelled turtles. They "excrete" oxygen, which for them is a waste product. Turtles excrete/poop wastes out there butt.

In many animals, salt must also be excreted.
Soft-shelled turtles from China can essentially expel pee from their mouths, researchers say.This odd ability may have helped them invade salty environments, researchers explained.Scientists investigated the Chinese soft-shelled turtle (The investigators bought soft-shelled turtles from the local Chinatown in Singapore and measured how much urea the reptiles excreted in their urine by sticking plastic tubes onto their hindquarters. Converting the nitrogen is beneficial to birds and reptiles because their bodies are then able to excrete these substances with a minimal loss of water. The excretory system allows the nitrogen to be excreted by the body before it begins to affect the pH of bodily fluids.
"The scientists conjecture that Chinese soft-shelled turtles excrete urea through their mouths instead of with their kidneys because of their salty environment.
