项目摘要

Five muricid species inhabit shallow tidepools dominated by the mussel Hormomya mutabilis in the rocky intertidal shore of Shirahama, Wakayama. Their behaviors were analyzed using a time-lapse video recorder in the laboratory and field to know the aspect of intra- and interspecific interactions among whelks. Morula musiva and Muricodrupa fusca attacked H.mutabilis by drilling a hole on a mussel shell. M.musiva sometimes robed a conspecific individual of a prey. Thais clavigera Form C attacked a mussel by inserting its proboscis between prey valves, and scavenged the flesh of a mussel remained or robed a predator of its mussel. Ergalatax contractus and Cronica margariticola seldom attacked a mussel, but depend on mussels opened by other predators, which includes both scavenging and kleptoparasitism. E.contractus sometimes attacked a conspecific or other whelk.Some experiments were conducted to know the effect of the existence of other species. The growth rate of E.contractus became higher when they were kept with M.musiva. On the other hand, the growth of M.musiva was not affected by the existence of E.contructus. M.musiva seemed to compensate the loss of kleptoparasitism with increasing the frequency of attacking.Very complicated intra- and interspecific interactions were seen among muricid species inhabiting the tidepools dominated by H.mutabilis. Especially, kleptoparasitism seems to play an important role there. To understand this unique whelk community further experiments and observations are needed.

在和歌山白滨的岩石潮间带海岸，五种muricid栖息在以贻贝Hormomya mutabilis为主的浅水潮池中。在实验室和野外使用延时录像机分析它们的行为，以了解海螺之间种内和种间相互作用的方面。桑螺（Morula musiva）和褐树蛙（Muricodrupa fusca）通过在贻贝壳上钻孔来攻击变形人。穆西瓦有时会将猎物的同种个体掠走。Thais clavigera Form C通过将其长鼻插入猎物瓣膜之间来攻击贻贝，并清除贻贝的肉，留下或剥夺其贻贝的捕食者。Ergalatax contractus和Cronica margariticola很少攻击贻贝，但依赖于其他捕食者打开的贻贝，其中包括拾荒和盗寄生。契约艾美耳球虫有时会攻击同种或其他种的螺，为了了解其他种的存在对螺的影响，进行了一些实验。与鼠耳蝠一起饲养时，缩绒螯蟹的生长速度更快。另一方面，M.musiva的生长不受Constructus的存在的影响。M.musiva似乎补偿损失的kleptoparasitism增加的频率attacking.Very复杂的种内和种间的相互作用，被认为是muricid种栖息在潮池占主导地位的H.mutabilis。特别是，盗寄生似乎发挥了重要作用。要了解这种独特的海螺群落，还需要进一步的实验和观察。
