寄生和共生物种可以影响生态群落的结构和功能，并且通常高度专业化以克服宿主的防御。在这里，我们报告了一个通常自由生活的物种的多个实例，蓝贻贝mytilus edulisLinnaeus， 1758，居住在海岸蟹carcinus maenas（Linnaeus, 1758）的鳃室中。共127C。研究人员从英吉利海峡的四个地点、爱尔兰海的一个地点和波罗的海入口处的两个地点对maenas进行了检查。三只螃蟹（一只来自英吉利海峡，两只来自瑞典的古尔马湾）的鳃室里长满了类似于鹦鹉螺属的贻贝。多酚黏附蛋白基因Me15/16位点测序证实为asM。可食的。双壳类侵染通常发生在较大的红色雄性个体中。每只贻贝可达16个，壳长2至11毫米不等，或嵌在鳃片之间，或附着在鳃腔内壁上。这是关于双壳类动物栖息在甲壳类动物鳃中的首次报道之一，也是一个通常自由生活的猎物物种侵扰捕食者的有趣案例。
Parasitic and commensal species can impact the structure and function of ecological communities and are typically highly specialized to overcome host defences. Here, we report multiple instances of a normally free-living species, the blue musselMytilus edulisLinnaeus, 1758, inhabiting the branchial chamber of the shore crabCarcinus maenas(Linnaeus, 1758) collected from widely separated geographical locations. A total of 127C. maenaswere examined from four locations in the English Channel, one location in the Irish Sea and two locations at the entrance of the Baltic Sea. The branchial chambers of three crabs (one from the English Channel and two from Gullmar Fjord, Sweden) were infested with mussels resembling the genusMytilus. Sequencing at the Me15/16 locus on the polyphenolic adhesive protein gene confirmed the identity asM. edulis. Bivalve infestation always occurred in larger red male individuals. Up to 16 mussels, ranging from 2 to 11 mm in shell length, were found in each individual, either wedged between gill lamellae or attached to the branchial chamber inner wall. This is one of the first reports of a bivalve inhabiting crustacean gills and is an intriguing case of a normally free-living prey species infesting its predator.
