generalists and <30% similarity with the more 

 specialized feeders. Generalists were often 

 collected at sites with other generalists and spe- 

 cialists. The tendency among specialized feeders 

 was one of low percentage similarity in both diet 

 and distribution. 



Other Species 



Four N. rossii, morphologically similar to N. 

 neglecta, consumed prey from six taxa. Amphi- 

 pods were most important by number (81%); krill 



(31%) and demersal fish (51%) were important by 

 volume. Krill was the most important component 

 by number and volume in the diets of five T. 

 eulepidotus, seven Pagetopsis macro pterus, and 

 eight Cryodraco antarcticus. These species con- 

 sumed prey from relatively few taxa and were 

 exclusively carnivorous. Trematomus eulepidotus, 

 morphologically similar to T. scotti, in addition 

 to the pelagic krill, also consumed cumaceans 

 which are typically associated with mud 

 bottoms. The channichthyids, P. macropterus 

 and C. antarcticus also consumed fish, such as
