The Corallimorpharia are a group of softbodied anthozoans closely related to the scleractinian corals. Although numerous reports have documented the agonistic behaviors of actiniarians and hard corals, only Chadwick (1987) has shown such behaviors in a corallimorph (Corynactis california). The following investigation confirms the use of inducible aggressive structures in space competition in the laboratory and in the field by Discosoma sanctithomae. This tropical corallimorph used both modified marginal tentacles and mesenterial filaments to damage adjacent scleractinians. All colonies of Agaricia agaricites transplanted near D. sanctithomae were damaged. Initially, D. sanctithomae adjacent to Meandrina meandrites were severely wounded. However, 67% recovered and retaliated within a one to six month period, causing damage to M. meandrina that persisted for at least twelve months.
珊瑚藻目是一类与石珊瑚关系密切的软躯体珊瑚虫纲动物。尽管有许多报告记录了海葵目动物和硬珊瑚的攻击行为，但只有查德威克（1987年）展示了珊瑚藻（加利福尼亚棒螅）的此类行为。以下研究证实了圣托马斯盘珊瑚在实验室和野外的空间竞争中使用可诱导的攻击结构。这种热带珊瑚藻利用改良的边缘触手和肠系膜丝来损伤相邻的石珊瑚。移植到圣托马斯盘珊瑚附近的所有扇形鹿角珊瑚群落都受到了损害。最初，与满月珊瑚相邻的圣托马斯盘珊瑚受到了严重伤害。然而，67%的圣托马斯盘珊瑚在1至6个月内恢复并进行了反击，对满月珊瑚造成的损害持续了至少12个月。
