Dentaries 
The dentary is the largest bone of the lower jaw and 
bears teeth in many fishes. The posterior region of 
the dentary is attached directly to the angular and 
articular bones. The left and right dentaries are fused 
anteriorly at the mandibular symphysis. The 
dentaries of the fishes examined here can be differ- 
entiated by the presence or absence of teeth and by 
the relative lengths of the body of the dentary and 
the dorsal and ventral processes. 
The dentaries of silver hake and red hake each 
possess a row of separate conical teeth extending 
slightly onto the dorsal process. Teeth are curved 
inwards and spaced relatively far apart (Fig. 3, A 
and B). The ratios of the lengths of the dorsal and 
ventral processes to the length of the body of the
