The mostly clear or yellow adipose fin has a dusky band that almost extends to the edge. The pectoral spine is short with 4-5 large teeth on the rear edge and small teeth on the front edge. The caudal fin has a straight edge and is joined to the adipose fin with a shallow notch between the two fins. The anal fin has 12-14 rays. To 2 ¾ in. (7.3 cm) total length.
