Intraspecific aggressive interactions have been observed in the scleractinian coral Stylophora pistillata. Extensive field observations suggest that intraspecific interactions result in the formation of necrosis in one of the two competing colonies. The formation of necroses is primarily restricted to those layers that are interspersed with polyps. In a second phase the non-living, central corallum is destroyed by foreign microorganisms. In some cases the necroses are resealed again, either by a living septal layer or by a calcareous plug. Evidence is presented indicating that the enzyme carbonic anhydrase has a role in these activities. First, it is involved in the apical growth of the colony. Using a semiquantitative assay procedure, the highest enzyme level was determined in polyps at the tips of the branches; lower levels were measured in polyps of the foot/trunk region. Secondly, the enzyme was found to be induced in those areas that are in close contact with non-isogeneic tissue. From these data we conclude that carbonic anhydrase is involved in the process of autolytic digestion in response to intraspecific contact of two non-clonemates.
在石珊瑚鹿角杯形珊瑚中观察到了种内攻击性行为。广泛的野外观察表明，种内相互作用会导致两个竞争群体中的一个形成坏死。坏死的形成主要局限于那些散布着珊瑚虫的层。在第二阶段，无生命的中央珊瑚骨骼被外来微生物破坏。在某些情况下，坏死部分会再次被封闭，要么是通过活的隔膜层，要么是通过钙质塞。有证据表明，碳酸酐酶在这些活动中起作用。首先，它参与群体的顶端生长。使用半定量测定程序，在分支顶端的珊瑚虫中测定到最高的酶水平；在足部/躯干区域的珊瑚虫中测得的水平较低。其次，发现该酶在与非同基因组织紧密接触的区域被诱导。从这些数据我们得出结论，碳酸酐酶参与了对两个非克隆体种内接触的自溶消化过程。
