Why are sharks urea?
Urea and trimethylamine in their blood and tissues help maintain their osmotic balance. They don’t have an ordinary urinary tract, So they concentrate urea in the blood and excrete it through the skin. Therefore, sharks, as well as most other cartilaginous fish, have urea.
Why are marine fish urea?

Frogs are cold-blooded, which means their bodies are the same temperature as the surrounding air or water. When they are cold, they lie in the sun to keep warm, and when they get too hot, they go into the water to cool their bodies.
Why are frogs called ureteral animals?
Because they secrete urea as the main nitrogenous waste, they are called ureteral animals. … In addition to mammals, urea is also present in the urine of amphibians and some fish. Interestingly, tadpoles excrete ammonia but switch to urea production during metamorphosis.
Why do sharks have ammonia?
Sharks are not ammunition, but they are ureteral animals. Urea animals excrete urea rather than ammonia as the main nitrogenous waste. Sharks need to avoid body water loss, so they cannot excrete ammonia because it needs enough water to be eliminated.
