Overabundance nan COTS ak Drupella ka akselere byolojik, redwi koray kouvri, diminye topografik konpleksite, ak kondwi faz deplasman soti nan koray algal dominasyon sou yon resif. Malgre ke eri lanmè yo tou predatè koray (paske yo entame sou koray yo ak jwe yon gwo wòl nan byoezyon), yo tou se seryezman enpòtan èbivò sou resif koray.

Overabundance of COTS and Drupella can accelerate bioerosion, reduce coral cover, reduce topographic complexity, and drive phase shifts from coral to algal-dominance on a reef. Although sea urchins are also coral predators (because they graze on corals and play a major role in bioerosion), they are also critically important herbivores on coral reefs.
