Discussion 



The flatfishes examined in this study comprised 

 two distinct feeding types based on the species 

 composition of prey and the frequency of occur- 

 rence of major food items. Parophrys vetulus, G. 

 zachirus, and L. bilineata were benthophagous, 

 feeding on benthic infaunal and epifaunal in- 

 vertebrates, mainly polychaetes, amphipods, and 



ophiuroids. Eopsetta jordani and C. sordidus were 

 piscivorous and fed more on pelagic animals, 

 consuming mainly fishes in addition to shrimp, 

 mysids, euphausiids, and cephalopods. Fishes did 

 not occur in the stomachs of the benthic inverte- 

 brate feeders, except for two fishes found in G. 

 zachirus. 



Differences were sometimes obvious in the food 

 habits of fishes within each feeding type. The
