Question

Name the excretory product of the marine fish.​

Answer 1

Answer:

Urea

EXPLANATION:

The osmoregulatory problems of freshwater fishes are different from those of marine fishes. the body floats of a Bony fish have salt concentrations intermediate between seawater and freshwater, show a marine fish is hypotonic and a freshwater fish is hypotonic to its environment. The invertebrate ancestors of fishes evolved in the oceans and had body fluids that were isotonic to seawater. Bony fishes, however , evolved in lakes and rivers and so different body fluids that are less salty than those of their invertebrate ancestors but are more salt than freshwater. some of these Bony fishes then return to oceanic habitats and excreted urea to maintain salt concentration in the body.so, excretory product of marine Bony fishes urea.
