摘要一些淡水和咸水腹足类，包括侧角腹足类、Vivipalidae和Neritidae，当它们的居民仍然活着并且繁殖活跃时，它们的壳显示出相当大的退化，使它们看起来像死的或空的壳。虽然这些贝壳的磨损外观可能是它们倾向于溶解在贫钙水中的必然结果，但腹足类动物可能会调整它们在贝壳钙化方面的投资，以允许适度的贝壳腐蚀。腹足动物生活的栖息地保留了许多旧的空壳，并且，通过在外观和纹理上模仿这些废弃的庇护所，外壳被腐蚀的腹足动物可能会避免捕食者使用视觉和触觉线索来定位猎物的发现。类似的行为，即动物利用同种祖先的生态位结构来伪装成废弃的旧住所，也可能在其他动物群体中发现，如卷叶毛虫、叶甲虫和石灰岩栖息地上的陆生蜗牛。
ABSTRACT The shells of some freshwater and brackish-water gastropods, including species of Pleuroceridae, Vivipalidae, and Neritidae, show considerable deterioration while their inhabitants are still alive and reproductively active, giving them the appearance of dead or empty shells. Although the worn-out appearance of these shells may be an inevitable outcome of their tendency to dissolve in calcium-poor water, it is possible that the gastropods adjust their investment in shell calcification to allow for moderate shell corrosion. The habitats where gastropods live retain many old, empty shells, and, by mimicking these disused shelters in appearance and texture, gastropods with corroded shells may avoid detection by predators using visual and tactile cues to locate prey. A similar behaviour, whereby animals use niche construction by conspecific antecedents to masquerade as old deserted dwellings, may also be found in other animal groups, such as leaf-rolling caterpillars, leaf beetles and land snails on limestone habitats.
