Brook Trout are easily recognized and distinguished from other trout by vivid white lines on the front or leading edge of the lower fins, and the top portion or back is covered with light wormy streaks or mottlings on a darker background called vermiculations. The dorsal fin has ten rays and is also strongly mottled. The vomer is trough-shaped, with the teeth restricted to the front portion. Brook trout feel soft to the touch because of the very small scales that cover the whole body. About 230 scales are along the lateral line, and they are more deeply embedded than other trout in the genus Salmo.
