HOBSON; FEEDING RELATIONSHIPS OF FISHES 



Figure 7. Outer drop-off habitat. Most of the fishes shown in the water column are Acunthurus thompsoni. 



Fishes Observed on Transect Lines 



All fishes observed on transect lines in the five 

 Kona habitats are listed in Table 7, where the 

 value given for each species in each habitat is the 

 relative abundance index, as defined in the 

 methods. Transect data for each habitat category 

 (number of transects, total number of species ob- 

 served, and mean number of individuals on a 

 single transect) are given in footnotes 2 to 7.

This study treats only teleostean fishes, as these 

 were almost the only kind observed on Kona reefs 

 during this study. Elasmobranchs occurred infre- 

 quently and seemed to have little impact on the 

 reef situation. No marine animals are more prom- 

 inent than sharks in Hawaiian lore (e.g. Hobson 

 and Chave, 1972), yet compared with most other 

 tropical Pacific Islands, relatively few sharks are 

 seen in Hawaiian nearshore waters today.
