Gadines have three dorsal fins and two anal fins. The distances 

 (number of intemeural bones) between dorsal fins 2 and 3 and 

 between anal fins 1 and 2 vary among genera. In all genera, the 

 dorsal and anal fins are separate from the caudal fin. The lower 

 branch of the posttemporal tends to become more elongate than 

 in lotines or phycines (longest in Arctogadus and Micromesis- 

 tius), the postcieithntm always has an expanded distal head, and 



the posterior process of the basipterygia tends to be short or 

 even lacking. Predorsal bones are absent in Gadinae. The first 

 and second dorsal fins are not usually internally continuous, but 

 the second and third dorsal fins are always internally continuous. 

 The neural and haemal spines on PU, are distally flattened in 

 all gadine genera and only three hypural bones (including the 

 parhypural) are present (Table 82, Fig. 151).
