Fin Development (Tables 1-3). — The adult com- 

 plement of 17-19 (usually 18) pectoral fin rays is 

 present in the smallest larva (9.9 mm). Pectoral 

 fin length increases from 17 to 26% SL between 

 flexion and benthic juvenile stages. The smallest 



larvae (—10 mm) have the adult pelvic fin com- 

 plement (1,5). Pelvic fin length is moderate, in- 

 creasing from 10 to 18% SL between flexion and 

 benthic juvenile stages. Pelvic spine length in- 

 creases from 6 to 12-14% SL. 



The adult complement of 8 + 7 principal caudal 

 fin rays can be counted on the smallest (9.9 mm) 

 flexion larva. Seven benthic juvenile S. entomelas,
