Here's an unfounded explanation:
One should also consider that for most organisms it is more important to get
CO2 out than to get O2 in. The byproducts of anaerobic respiration would
quickly drop blood pH, unless a quick means of getting rid of acid is
available, CO2 through the skin is one.

Another totally unfounded theory:
As far as the tail-in-water that started the thread, it seems more like a
defense mechanism. On the attack of a land predator, a flick of the tail
would send the fish in one direction and droplets of water in another. There
is a significant probability the predator will go after the wrong shiny, fast
moving blob.
