生物侵蚀对珊瑚礁的形态和破坏很重要。棘虫作为食草动物和穴居动物对珊瑚礁的侵蚀有重要作用。对埃尼韦塔克环礁上两种主要穴居棘虫（马氏棘虫和针孔棘虫）肠道内容物的循环所做的研究表明，两种物种的总CaCO侵蚀范围在80-325克/年之间，估计每年在埃尼韦塔克环礁上产生的CaCO总量为4000克/年。在这种情况下，Enewetak上的棘虫类可以占环礁生物侵蚀总量的2%至8%。与其他生物相比，棘足类生物可能被认为是重要的生物侵蚀者；例如，海绵C/iona是一种主要的生物侵蚀剂，可以破坏Enewetak上每年总CaCO产量的25%。每日平均每人的侵蚀率（g durchin-'）范围从0.1到0.2 e.m aaei和0.2到0.4英镑。acicu /前提。
Bioerosion can be important to the configuration and destruction of coral reefs. Echinoids as grazers and burrowers can contribute significantly to coral reef erosion. Studies done on the turnover of gut contents of the two major burrowing echinoids on Enewetak atoll (Echinometra mathaei and Echinostrephus aciculatus) show a range of total CaCO, erosion by both species from 80-325 g m-y• An estimated total of 4000 g m-2yof CaCO, is produced annually on Enewetak. In this case, echinoids on Enewetak can contribute from 2 to 8% of the total bioerosion on the atoll. Echinoids may be considered important bioeroders when compared with other organisms; the sponge C/iona, for example, a major bioeroder , can destroy as much as 25% of the total annual CaCO, production on Enewetak. The daily mean erosion rates per individual (g durchin-') range from 0.1 to 0.2 for E. mathaei and 0.2 to 0.4 for£. acicu/atus.
