Minnows are the largest fish family in North America, with more than 230 species. Most minnows are small, and many species look alike. Minnows have no teeth in their mouths; instead they grind their food with highly specialized teeth in their throats. During the breeding season, the males of many minnow species develop small, hornlike points called breeding tubercles. The size and location of these tubercles can be useful in recognizing species. Minnows are seen in many lakes and streams in North America. The Common Carp is a Eurasian minnow that was introduced into the United States in the early 1800s. It is still often used as food.
