Illinois is home to a wide variety of fish species. At present 34 families of fishes are represented in the state's waters. Because so many species exist, the fish exhibit a wide range of habits and characteristics. The information contained in these pages is Illinois specific as much as possible.
Unlike the silvery fishes of the sunlit and upper twilight zones, most bathypelagic fishes are dark brown or black, presumably to avoid reflection of bioluminescence. Some bathypelagic fishes even achieve “blackness” by being red, a strategy made possible by the absence of red light at depth.

The resulting bathypelagic, or midnight, zone extends to about 4,000 meters (about 13,100 feet), which reaches the ocean floor in many places. In addition to the lack of light, the midnight zone is characterized by a steady temperature of around 4° Celsius (39° Fahrenheit).
When bluegills or other sunfish are overpopulated and crowded, they prey on bass eggs and fry and prevent bass from reproducing successfully. Birds do not stock ponds with fish. Fish eggs eaten by birds are quickly digested. Eggs that cling to the bodies or feet of birds would not survive a long flight through the air.
