LARVAE INFORMATION

Hatch Size (min-max in mm SL):
Preanal Length (%SL): 50 - 75
Flexion Length (in mm SL): Complete at 10.6
Length at Transformation (in mm SL): 24 - 33
Fin Development Sequence: Caudal and pectorals, pelvics, dorsal and anal
Larval Pigment Regions: In each developmental larval stage, pigment is present in the regions listed below
(click for pigment regions)
Yolk-sac: mouth, crown, nape, dorsal gut, lateral gut, ventral gut, ventral,
Preflexion: mouth, crown, nape, dorsal gut, lateral gut, ventral gut, caudal finfold, pectoral fin, ventral,
Flexion: mouth, crown, nape, cheek, dorsal gut, lateral gut, caudal finfold, pectoral fin, dorsal, ventral, mediolateral, caudal,
Postflexion: mouth, crown, nape, cheek, dorsal gut, lateral gut, caudal finfold, pectoral fin, dorsal, ventral, mediolateral, caudal,
Juvenile: mouth, crown, nape, cheek, dorsal gut, dorsal finfold, caudal finfold, pectoral fin, dorsal, ventral, mediolateral, caudal,
Pigment Diagnostics: Dorsal midline pigment heavier than ventral midline pigment; pigment on hypural margin
Diagnostic Characters: Distinguished from Sebastes flavidus by: high pectoral-fin ray count (usually 19), fewer lateral line pores (usually <50), deeper and shorter caudal peduncle


PELAGIC JUVENILES

Body pigment heavy and diffuse, pigment blotch on last few dorsal-fin spines, lateral midline pigmented; juveniles are pelagic at 40-50 mm SL
