Outbreaks of corallivorous gastropods, such as Drupella spp. (Neogastropoda: Muricidae), are well documented as leading causes of coral mortality. Recent years have provided numerous records of outbreaks of Drupella spp. worldwide, impacting the resilience of coral reefs (McClanahan, 1994; Cumming, 2009; Kaullysing et al., 2017; Scott et al., 2017b). Drupella spp. are obligate corallivores having a preferential diet of stressed live scleractinian coral tissue, especially acroporids (Morton, Blackmore & Kwok, 2002; Rotjan & Lewis, 2008; Al-Horani, Hamdi & Al-Rousan, 2011). These snails, which are known to be attracted to conspecifics and the chemical cues in mucus secreted by stressed or damaged corals, often form dense aggregations (Morton et al., 2002; Moerland, Scott & Hoeksema, 2016). Following extensive bleaching events, Drupella spp. have been reported to shift their dietary preference temporarily from branching acroporids to solitary fungiids (Hoeksema, Scott & True, 2013).

毛里求斯Drupella在原位卵沉积中选择了多种基质，这是西印度洋的首次记录

珊瑚状腹足动物的暴发，例如Drupella spp。（Neogastropoda：Muricidae），是珊瑚死亡的主要原因。近年来提供了许多有关Drupella spp爆发的记录。在世界范围内，影响了珊瑚礁的复原力（McClanahan，1994; Cumming，2009; Kaullysing等人，2017; Scott等人，2017b）。德鲁佩拉spp。它们是专性生活在珊瑚礁中的珊瑚虫，它们的饮食主要是强调活的巩膜珊瑚，尤其是丙烯醛（Morton，Blackmore＆Kwok，2002; Rotjan＆Lewis，2008; Al-Horani，Hamdi＆Al-Rousan，2011）。众所周知，这些蜗牛会被特定物种所吸引，并且应力或受损珊瑚分泌的粘液中的化学线索通常会形成密集的聚集体（Morton等，2002; Moerland，Scott和Hoeksema，2016）。经过广泛的漂白事件，Drupella spp。据报道，他们的饮食偏爱暂时从分支的顶孢类转变为单独的真菌类（Hoeksema，Scott＆True，2013）。
