Figure 1. — Embryo and newly hatched larva of Sphyraena borealis. A. Embryo; B. 

 Newly hatched larva, 2.6 mm SL. Inclusions in the finfold are not pigment. 



teeth were strong and caninelike; most were 

 slightly curved and directed backward at their 

 tips. The number of premaxillary teeth in- 

 creased from 4 at 5.3 mm SL to about 20 at 21.5 

 mm SL. Lower jaw teeth increased from 11 

 at 9.4 mm SL to about 15 on specimens from 

 12.1 to 21.5 mm SL. Palatine teeth numbered 

 6 at 9.4 mm SL and increased to about 10 at 

 21.5 mm SL. 



Eye Diameter 



Eye diameter decreased slightly, from 8% SL 

 on newly hatched larvae to 7/r SL for most in- 

 dividuals longer than 16.9 mm SL (Table 1). 



Myomeres 



The number of myomeres was constant at 24 

 (14 preanal plus 10 postanal) throughout de- 

 velopment.
