Micropterus salmoides (Largemouth Bass)

Micropterus salmoides, or largemouth bass, is a species of freshwater gamefish that comes from the sunfish family, and is native to North America. It is normally about 18 inches long, but it can grow over 24 inches.

Regardless of this large number of names (which include trout), this fish (has its most common name applies) is a bass. One reason for its name 'black bass' is thus of its genus, Micropterus, which its members are called black basses (black bass for singular).

It was originally native to some 10-20 states from the U.S., but then where introduced to the hole and all the states of the United States of America. It is one of the few basses that are part of the sunfish family. This fish has two recognized subspecies, the Florida and the Northern ones, which easy crossbreed in the wild with each other. The only way to find out if a largemouth bass is itself, a Florida one, or a Northern one is by doing a number of tests to truly identify them.
