ocean, more work is needed on the food habits 

 of poorly studied pelagic predators such as 

 sharks, porpoises, gempylids, and squids. 

 Further attempts, such as those of Forster 

 (1971), to collect potential mesopelagic preda- 

 tors are also needed. 



ACKNOWLEDGMENTS 



I am grateful to all the people who struggled 

 with the trawls day and night during the 

 work at sea. Among the many who assisted 

 are A. R. Hartmann, D. M. Kuba, T. Okamura, 

 J. P. Vansant, and D. A. Ziemann. I also 

 thank Captain Red Scholtz and the crew of 

 the venerable RV Teritu. 



The comparative series between IK and CT 

 was made possible by the cooperation and 

 assistance of the Southeast Fisheries Center, 

 Honolulu Laboratory, National Marine Fish- 

 eries Service, NOAA. B. E. Higgins was in 

 charge of the RV Townseyid Cromwell 

 operations. 



Numerous others assisted in sorting the 

 samples; special thanks are due to Barbara 

 Baldwin and Kay Koons. Patricia Wagner 

 assisted in all phases of the work. I am par- 

 ticularly grateful for her conscientious and 

 careful efforts. I also thank John Caperon 

 for use of his computer facilities. B. G. Naf- 

 paktitis and R. L. Wisner assisted in identifi- 

 cation of specimens, and the latter kindly made 

 available a very useful unpublished manuscript. 

 R. E. Young critically reviewed the manuscript 

 and made helpful suggestions. 



This research was supported by NSF Grant 

 GB-23931 and funds from the University of 

 Hawaii, Hawaii Institute of Marine Biology.
