The Sauger is a freshwater fish that is bronze to olive in color with dark color blotches and has a white belly. It has an elongated body and has two dorsal fins; the first dorsal is spined while the second fin is soft-rayed. One of the ways to differentiate it from its closely-resembled relative, the walleye, check its tail if it has a white-tipped. If the white-tipped tail is absent, then it is a sauger. The sauger sometimes mates with its close relative, the walleye. The hybrid species is called "saugeye".
