The Nephron of a Freshwater Fish

freshwater fish is to get too much water pushed into it by osmosis. Water wants to travel to an area where there's a high concentration of stuff dissolved in it. Freshwater fish have adapted or evolved a kidney like structure to have a big glomerulus. And just the force heaps have flew it out of it. So you can just pee all the time. Because it just wants filtration to occur at all times. It just has to get rid of all this free water. Does it make sense? It does.
