Compare & explain differences of terrestrial mammals, marine & freshwater fish in urine concentration

In this dot point, i know how to compare b/w the urine con. of all of them. But is there another explanation, other than the condition of their environment, as a reason to explain the differences of their concentration? I've already checked the bio resources & my heinmann txt book.

The environment is the only one i used ie:

Terrestrial mammals - concentration varies with the environment, eg desert = highly concentrated for water preservation

Freshwater - excrete large quantities of dilute urine as water tends to diffuse into the organism

Marine - excrete small quantities of concentrated urine as water tends to diffuse out of the organisma and salts diffuse in

I think the explaining part wants you to explain why they have such different urine concentration. Look for the enviroments in which these three categories of animals lives
