The Stonecat is yellow to slate above, with a light blotch on the nape, a cream-white spot at the rear of the dorsal fin base, and a cream-white blotch on the upper edge of the caudal fin. Unlike other madtoms, the premaxillary tooth patch has a backward extension from either side. The rear edge of the pectoral fin spine has no or only a few small sawlike teeth. The Stonecat is slender, has a straight edge on the caudal fin, and 15-18 anal rays. To 12 1/4 in. (31 cm) total length.

Range

The Stonecat is found in the St. Lawrence-Great Lakes, Hudson Bay (Red River) and Mississippi River basins from Quebec to Alberta, and south to northern Alabama, northern Mississippi, and northeastern Oklahoma. On the Atlantic Slope, it is found in the Hudson R. drainage of New York. The species is common throughout much of its range.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
