The mudminnows and pike group is a small group of freshwater fish, including 5 species of mudminnows and 5 species of pikes. This group is found only in the northern parts of the Northern Hemisphere, including northern North America and Eurasia. Pikes are long, streamlined, predatory fish, capable of great bursts of speed. They are voracious, and will eat almost anything they can get into their mouths. Pikes are popular with sport fisherman, because they put up a big fight when caught and can grow to be quite large. Mudminnows are smaller than pikes, but are also efficient predators that capture prey by ambushing them with speed.
