the owls are not what they seem

I just, voluntarily, wrote an essay for my friend, on the internal organ systems of fish and its differences/similarities to the ones of mammals. I think I have too much free time and/or am just too nice and eager to serve/help. He was very thankful though and I think I gained a shitload of karma.

Also, if there’s anything you’d like to know about fish poo or gills, you can ask me.
