The banded sculpin may attain a length of two and one-half to ﬁve inches. Its back and sides are brown, green or red-brown with four or ﬁve dark saddles. The belly is yellow-white with dark specks. The pelvic ﬁns are white, while the other ﬁns are dark. The lateral line is complete. This ﬁsh lives about six years.
The banded sculpin may be found in the southern tip of Illinois and in the Ohio and lower Mississippi rivers in Illinois. This ﬁsh lives in rock and gravel areas in creeks and rivers. The banded sculpin spawns in spring. The male prepares a nest under a rock and stays with the eggs and young until they leave the nest. The female turns upside down to lay eggs on the roof of the nest chamber. More than one female may lay eggs in the same nest. The eggs hatch after three or four weeks. This ﬁsh hides under rocks during the day. It feeds on the bottom at night, eating crayﬁsh, immature insects, small ﬁshes and snails.
