Identification

The Snail Bullhead has a flat head and a decidedly rounded snout. The body is yellow-brown or olive above and blue-white to white below. There is a large dark blotch at the base of the dorsal fin. The fins are dusky olive-brown, and all except the pectoral fin have a narrow black edge. Some populations (e.g., in the St. Johns River in Florida) are strongly mottled. The rear edge of the pectoral spine lacks sawlike teeth. The anal fin is short and rounded with 17-20 rays. The first gill arch has 14-17 rakers. To 11 1/2 in. (29 cm) total length.

Range

The Snail Bullhead is found in Atlantic Slope drainages from the Dan River in southern Virginia to the Altamaha River in Georgia, and on the Gulf Slope in the Apalachicola River drainage in Georgia, Alabama, and Florida, and the upper Coosa River system in northern Georgia. An isolated population lives in the St. Johns River in Florida. The Snail Bullhead is common in 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.
