the fishes has to use kidneys because most fish are ectothermic which means that they are cold blodded so if they dont have kidneys then how are they going to have babys and swim. this is why fish use kidney but i you dont trust me then go to Google then go to images and type in your question or so then they will show you fishes with no kidney and where do they put them and everything.
An opisthonephric kidney is the functional kidney of anamniotes, fish, and amphibians.
A horseshoe kidney is a congenital condition where the two kidneys are fused together at the lower end, forming a horseshoe shape. This condition does not usually cause symptoms and may go unnoticed, but in some cases, it can lead to complications such as kidney stones or urinary tract infections. Monitoring and management may be required if complications arise.
The kidney filters waste from the blood stream and body for urinary excretion.
Anderson-Carr kidney, also known as "fused renal ectopia," is a rare congenital condition where the kidneys are fused together during fetal development, resulting in a single, often horseshoe-shaped kidney. This condition can lead to various complications, including obstruction, urinary tract infections, and impaired kidney function. Diagnosis typically occurs through imaging studies, and treatment may involve monitoring or surgical intervention depending on the severity of symptoms.
Not every fish have to be alike. A Puffer fish has gills,4 fused teeth, a beak-like mouth, and a stretchy stomach. A Puffer fish has gills so it is indeed a fish. All fish have gills.
It's most likely prevent because of eatting too much Fish. Fish oil improves blood lipid profiles and decreases the risk of kidney disease. ~ Hope that helped.
The kidney system is responsible for removing waste in fish.
Ornamental fish can develop kidney stones primarily due to poor water quality, improper diet, and genetic predisposition. High levels of minerals, particularly calcium and phosphorus, in the water can lead to imbalances that promote stone formation. Additionally, a diet lacking in variety or rich in certain nutrients can contribute to kidney issues. Stressful conditions and underlying health problems can also exacerbate the risk of kidney stones in these fish.
Blueish: somewhat blue Fusible: capable of being fused or melted
Fused silica has 2 meanings: previously fused silica and presently fused silica. Previously fused silica is fused by heating it to its melting point. This can be done in crucible in a furnace. Presently fused silica is already hot and fused. Note: melted silica is probably a conductor, at least melted glass is a conductor.
Mesonephric kidneys are the primitive excretory organs found in fish and amphibians, while metanephric kidneys are the more advanced excretory organs found in mammals, including humans. Metanephric kidneys filter blood to produce urine through nephrons, while mesonephric kidneys mainly function to remove waste products from the blood.
They can regenerate lost body parts and even their brain, heart and kidney!
