Figure 2. Distribution of total herbivore biomass across body-size classes and dominant herbivore species (n = 3315).

(a) Average (±SEM) biomass of the diminutive urchin (E. viridis) and striped parrotfish (S. iseri) versus all other herbivores with inset photograph from STRI Point study site depicting typical E. viridis activity on a dead coral head during the day (Photo credit: C.D.K.), (b) average relative body size (±SEM) comparison of herbivorous parrotfish and urchins found at our study sites and (c) total biomass pooled across sites within each body-size class. The sample size (n) is denoted in each figure, respectively.
