White Sucker (Catostomus commersoni)
A doppelganger for the longnose sucker, the white sucker also mimics the longnose sucker's actions and habits to a tee. With a toothless smile perfect for its bottom-feeding diet, the white sucker spends most of its time in warm, shallow waters. You will find these fish near obstructions and windfalls that create divets in Great Lakes bays, estuaries, and tributaries, but a search in deeper Lake Superior waters will garner a white sucker spotting, too. As an adult predator when lake trout are scarce, sea lampreys prove a challenge to this fish's existence, as it has for the longnose sucker. The white sucker is no wannabe of its longnose relative, though; it's its own fish, and it's quite happy to have it that way.
