✦ Synopsis

Among the five species of parrotfish studied, only large Sparisoma viride (and rarely large Scarus vetula) graze on live coral. Of the several species of corals grazed, Montastrea annularis is grazed most extensively, and variations in its form may be the result of grazing scars. Parrotfish feeding on algae a t the bases of the corals Madracis mirabilis and Porites porites break off the corals. This attack causes recession of the stands of M . mirabilis a t an average rate of 1 cm/month.

The effect of the ratio a/W on the values of 6i and Ji in a structural steel has been studied by measuring the crack-opening displacement and J-integral at initiation in three-point bend specimens with shallow and deep notches and by the finite element method. It is shown that the values of Si and J
