Summary: 
(A) Diadema setosum a grazing echinoid linked to major erosion of western Indian Ocean reefs (Photo: O. Hoegh-Guldberg). (B) Echinostrephus sp., sitting in its home scar that it has created (Photo: O. Hoegh-Guldberg). (C) Experimental study of bioerosion at Osprey Reef, Coral Sea, two replicate grids with newly laid coral blocks to be exposed for varying lengths of time (Photo: J. Johnson). (D) Diagrammatic representation of coral block illustrating how the various components of bioerosion (i.e. grazing, accretion and boring) are determined from a series of sections through each block. Knowing the density of the coral block, these measurements can then be scaled up to rates per square metre and then net rates of bioerosion calculated: a, original block; b, accretion; c, block remaining after grazing and boring (Image: K. Attwood).
