 ^The second spine. 



fifth or sixth in juveniles 



develop strong serrations. Spines in the anterior 

 preopercular series are much shorter than those in 

 the posterior series. The second or middle spine is 

 present only in larvae prior to completion of 

 notochord flexion. <10 mm. Its appearance as a 

 spine changes to a small bump which then fuses 

 with the ridges connecting it to the third preoper- 

 cular spine of the posterior series- The first and 

 third anterior spines are present on larvae 

 through pelagic juveniles of =23 mm and then are 

 no longer visible- 



The superior and inferior opercular spines and 

 the interopercular spine appear by the time the 

 larvae reach 12 mm, although percursor bumps 

 may be seen as early as 9 mm. These spines persist 

 into the juvenile stage. The subopercular spine is 

 present in juveniles >78 mm. 



Around the eye, the ridge anterior to the post- 

 ocular spine becomes serrated at 10.6 mm. These 



serrations disappear at the time of supraocular 

 spine formation, >21 mm. The preocular spme 

 begins to appear in transforming specimens >16 



mm and is strongly formed by the time fish are 20 

 mm. Beneath the eye the second spine of the in- 

 ferior infraorbital series forms in larvae >10 mm. 

 The fourth spine of the superior infraorbital series 



develops under the posterior third of the eye on 

 larvae >13.6 mm and it persists through the 

 juvenile stage as do the two inferior infraorbital 

 spines. The second and third superior and third 

 inferior infraorbital spines never develop. Tiny 

 serrations appear along a ridge between the first 

 and fourth superior infraorbital spines in speci- 

 mens 14.4 to 38.2 mm. The first spine of the 

 superior infraorbital series disappears in speci- 

 mens >50 mm. The nasal spine develops m larvae 

 of =10 mm and persists in juveniles.
