Dierking et al.: Diet composition and prey selection of Cephalopholis argus in Hawaii

Figure 5 
Comparison of the size distribution of prey fishes in the diet of Cephalopholis 
argus (dark gray bars), and of the same prey taxa observed during under- 
water visual surveys (WHAP surveys) on reefs in Kona (light gray bars), for 
all fishes combined, and for six of the most important families in the diet 
of C. argus (by %N). Sample sizes ( n ) in the upper half of each panel refer 
to the number of samples of each taxon found in C. argus stomachs, and in 
the lower panel to the total number of individuals of the taxon observed in 
WHAP surveys in 2003. Mean total lengths for distributions are indicated 
by arrows. P-values are outcomes of Kolmogorov-Smirnov comparisons of 
the two size distributions in each panel, and significant values indicate that 
distributions were different.
