Although the vast majority of the members of the sunfish family Centrarchidae have ten dorsal spines, members of the genus Pomoxis only have six to eight dorsal spines.  The reason for this is currently unkown; scientists do not feel that having less dorsal spines gives crappies any kind of evolutionary advantage.

Black crappies that live in lakes and streams in the northern United States tend to grow faster than those that live in lakes and streams in the southern United States.  Researchers think this may be because southern bodies of water have longer growing seasons and harder water than those in the north.

The black crappie is one of the few freshwater fish that does not 
hibernate in the winter.  As a result, it is a much sought after fish 
during the ice fishing season.  

Some other common names for Pomoxis nigromaculatus include 
calico bass, strawberry bass, and speckled crappie.  These names 
refer to the distinct speckled pattern on the body of the black
