Yolk-sac:
Preflexion: mouth, crown, nape, cheek, isthmus, dorsal gut, lateral gut, ventral gut, anal finfold, pectoral fin, dorsal, ventral, mediolateral,
Flexion: mouth, crown, nape, cheek, isthmus, dorsal gut, lateral gut, ventral gut, anal finfold, pectoral fin, dorsal, ventral, mediolateral,
Postflexion: mouth, crown, nape, cheek, isthmus, dorsal gut, lateral gut, ventral gut, dorsal finfold, anal finfold, pectoral fin, dorsal, ventral, mediolateral, caudal,
Juvenile:
Pigment Diagnostics: Larvae are pigmented over first quarter of the body, increasing laterally to the entire body except at tail tip; dorsal and anal finfolds and distal portion of pectoral fin unpigmented
Diagnostic Characters: Lack of head spines, prickles over body, globase morphology unlike any other cottid, loose outer skin, pelvic fin appears to be inserted in pockets of skin with only the tips exposed
