Scorpaenidae (Figs. 220-223).— This is the largest and most 

 diverse scorpaenoid family with about 44 genera and more than 

 350 species. The classification and relationships of the family 

 are in controversy (Washington et al., this volume) and we 

 follow their subfamily groupings. 



Sebastinae. — Barsukov (1981) includes 3 genera and 1 1 4 species 

 in this temperate and boreal group. Sebastes with about 106 



species accounts for almost '/3 of the species in the order. At 

 least a single larval stage is known for 62 species of Sebastes 

 and flexion or postflexion stages have been described for about 

 32 of these (Table 107). Larval stages have been described for 

 one of the 6 species oi Helicolenus and are unknown for the two 

 species of Hozukius. 



In Sebastes most of the yolk is utilized before hatching while 

 the eggs lie freely within the ovary. Hatching precedes extrusion 

 and newborn larvae range from 3.8 to 7.5 mm in length among 

 the various species and have functional eyes, jaws, and pectoral 

 fins. The finfold is slightly inflated and has minute cell-like
