Longnose Sucker (Catostomus catostomus)

Despite striking physical similarities, this fish is NOT the white sucker. Unique in its own ways, a love of algae, aquatic plants, and aquatic invertebrate (the ones at the bottom of the lake) defines this HooverTM of a fish. But if this "what you eat" definition isn't for you, maybe the "what eats you" definition is. This sucker provides all-too-necessary nutrition to the larger members of the fishy food chain, like walleye, trout, northern pike, and burbot. Whether it is near its home, the cold, clear waters of the northern United States and Canada — like Lake Superior — or closer to the rivers it has invaded in Asia's eastern Siberia, this longnose is a sucker, but NOT the white one.
