两个共生的不同共生物种在一个单一的细胞，以前不知道在任何后生动物的条件下共存，表现在鳃的大西洋中脊热液喷口贻贝（家庭Mytilidae）。分子系统发育分析和荧光原位杂交结果表明，鳃细菌细胞内的大型和小型共生体形态型是不同的细菌物种，这两种共生体物种隶属于硫自养和甲烷营养共生体，这些共生体先前在与深海热液喷口和碳氢化合物渗漏密切相关的贻贝的单种协会中发现。
The coexistence of two phylogenetically distinct symbiont species within a single cell, a condition not previously known in any metazoan, is demonstrated in the gills of a Mid-Atlantic Ridge hydrothermal vent mussel (family Mytilidae). Large and small symbiont morphotypes within the gill bacteriocytes are shown to be separate bacterial species by molecular phylogenetic analysis and fluorescent in situ hybridization, The two symbiont species are affiliated with thioautotrophic and methanotrophic symbionts previously found in monospecific associations with closely related mytilids from deep-sea hydrothermal vents and hydrocarbon seeps.
