Question

Are shark osmoconformers?

Answer 1

Hint: Osmoconformers are the marine organism that maintains equilibrium in the internal environment to that of the external environment. They maintain an interior salinity similar to their ambient conditions (e.g., most marine invertebrates, seagrass). It balances its osmotic pressure with that of its surrounding.

Complete answer:
The marine animals preserve the osmolarity of their internal fluid, with the goal that it is steady equal to the encompassing seawater. Osmoconformers decline the net influx of water into or out of their bodies from diffusion. It can keep the inside solute concentrations within their bodies at a stage that is equal to the osmolarity of the surrounding medium.

The blood of the shark is isotonic with the surrounding water. It means that the concentration of solutes in their body is the same as that of the surrounding. This helps in maintaining osmotic balance with the surrounding.

So, Shark is called an osmoconformer.

Additional Information: The freshwater organisms are called osmoregulators. The osmoregulators firmly regulate their body osmolarity, which persistently stays constant. The osmoregulatory successfully controls salt concentrations and they cannot withstand the salt concentrations in the environment. An example is a freshwater fish.

Note: Euryhaline organisms, organisms like the salmon and molly that can tolerate a quite wide range of salinity. The stenohaline is a freshwater organism and it will die in seawater, and in a similar way, most marine organisms are stenohaline, and can't live in freshwater. The osmoregulators cannot survive in a marine environment.
