Figure 5, 



A. Mean number of Spirorbis at four depths. Mean of 3 m 

 (inner) differs significantly from 30 m (outer) , and also 

 from 50 m, (inner and outer) , and 80 m (outer) (ANOVA, p < 

 0.05, 7, 33 df, F = 13.2) 50 m (inner and outer) also 

 differs from from 65 and 80 m (inner and outer), 30 m 

 (outer) differs from 65 and 80 m (inner and outer) , and 65 m 

 (inner and outer) differ from 80 m (inner and outer) . 



B. Mean numbers of Anomia sp. at four depths. None occur at 

 30 - 50 m. Means at 65 m (inner and outer) differ 

 significantly from 80 m (inner and outer) (ANOVA, p < 0.05, 

 7, 33 df , F = 9.4) . 



C. Mean percent cover of Filograna implexa at four depths. 

 Means at 80 m (inner and outer) differ significantly from 

 all other means, but not from each other (ANOVA, p < 0.05, 

 7, 33 df , F = 5.1) . 



D. Mean percent cover of Shizomarella auriculata at four 

 depths. Mean at 50 m (outer) differs significantly from all 

 others except 50 m (inner) (ANOVA, p < 0.05, 7, 33 df, F = 

 3.8). Mean at 80 m (outer) differs from all others except 

 50 m (inner and outer) .
