    Answer:

    AFAIK

    Explanation:

    uric acid is much less toxic than ammonia, hence bigger concentrations of it are tolerated in the body. This means you can excrete it while excreting very little water – beneficial wherever water’s not abundant.

    There’s a tradeoff though, uric acid requires more energy to synthesize than ammonia, so pretty much all fish, say, excrete ammonia rather than uric acid – it’s no problem to dilute ammonia since there’s no water shortage.
