Mizo

The mizo replaces its ancestor in Oz Temperate Coast. It has two big advances. Its primitive gills have now become much more effective and to filter-feed on microbes, that live on rocks, as the solumlift, mizo evolved a mouth underneath its body. With it mizo sucks microbes from the soil. And another minor change is its color. Now its blueish, like its environment. Nothing else is changed in it.
