Common name: Brown trout Non-native. ID: In lake runs and many great lakes region, the brown trout are actually silver in color. Broad, square tongue. 2 dorsal, 1 adipose fin. 11-12 large teeth. Covered in spots, but these often less predominate in lake-dwellers. Picture 1 and 2 are stream dwellers; image 3 is a lake dweller much like what you'd find in the great lakes. Life cycle: Reside near stream outlets in early summer, and move up to spawn in September and October. Female creates shallow depression in gravely area and lays eggs. Covered up and left to hatch. Live up to 13 or more years, and can be as big as 8lbs. Food source: insects and their larvae, crustaceans, mollusks, amphibians, small rodents and other fish Predators: Young fish can be hurt by larger fish and by predatory birds such as merganser.

Is there a reason the markings differ depending on where they live? Does it have to do with genetics or like with that they're eating~~? @mcgraffy
