Breeding males with hypertrophied odontodes on pectoral fin spines, which increase in length and density distally. Adipose-fin spine and caudal-fin spines also covered with hypertrophied odontodes. Caudal-fin rays also with odontodes in same manner, though not as large as on caudal-fin spines. Hypoertrophied odontodes also covering posteromedial edge of most plates along body. Longest plate odontodes occur on middorsal, median, and mid-ventral plate rows. Hypertrophied odontodes also present on opercle, along snout, cleithrum, posterior edges of head, and dorsal-fin spine.

Body base color light brown or tan. Base color darkens in largest specimens (breeding males). Spots oblong (not perfectly circular) on head and body. Greatest density occurs on head, with spots increasing in size posteriorly. Spots on head centered on anterior end of supraoccipital crest and radiate outward. Abdominal spots observed in some specimens and range from small spots with random distributions to large spots in columns. Paired fin spines with bands, with paired fins having random spots that are often fused together. Dorsal-fin spine with dark spots anteriorly; interradial membrane of dorsal fin with two rows of spots between each fin ray. Caudal fin with random spotting. Lower caudal fin lobe with dark coloration in large adults, with spots apparent.
