I build sims in Second Life or I used to. I have small one there and one of the things I often do is fill the sky with fish and sharks and whales. I once built a sola system with liveable planets and there were circling sharks and whales i my universe ... it is basically not home for me if there are no meerfolk in the sky :)

And if you have ever heard me sing i am many in one ....this is why these lines are mine now :)

and fishes, birds,
float either way
amongst the peaks,
change forms

I shall put them in my box of treasures :) see like the magpie I flew in cause you presented the shiny :)
