Answer:

Explanation:

Cartilaginous fishes that are also jawed vertebrates like rays, skates and sharks fall in the Chondrichthyes class. There is a high level of urea that has been developed in their blood.

This makes their blood isotonic to the sea water and thus their kidneys have to absorb more urea in the tubules than compared to what is done by human kidneys. Thus, they have to live in an osmotic balance with their environment.
