Table l.--Zooplankton collected over 1 m 2 of reef substrata at three depths. 

 Mean, standard deviation and percent of samples containing each organism 

 are given for the common categories of organisms. Samples from 6 m included 

 8 samples from 3 nights; those from 15 m included 27 samples from 7 nights; 

 and those from 24 m included 21 samples from 7 nights.

Figure 4 (opposite page) .--Volume frequency histogram for the three reef sites. 

 The number of samples of differing volumes (converted to volume/m 2 ) is plotted. 

 Volume is plotted in 2 ml increments with the midpoint volume indicated for 

 each.
