Juvenile:
Pigment Diagnostics: Distinguished from other hexagrammids by: lack of snout pigment
Diagnostic Characters: Distinguished from other heavily pigmented larvae except Hexagrammos spp. by: 58-63 total vertebrae, pigment widely distributed on dorsal head and gut, pigment above and below notochord, gut length <50% SL. Distinguished from other hexagrammids by: unpigmented snout, larger eye, shorter snout
