Which of the Following are Typically Osmoconformers

Question

Which of the following are typically osmoconformers?
A) marine teleost fishes
B) freshwater invertebrates
C) freshwater teleost fishes
D) sharks

Accepted Answer

Osmoconformers are organisms that maintain their internal osmotic pressure at equilibrium with their external environment. Sharks, which are marine animals, are known to be osmoconformers. They achieve this balance by retaining high concentrations of urea and other substances in their blood to match the osmotic pressure of the seawater, thereby avoiding the loss or gain of water from their bodies.
