中文摘要：

测定了湖北梁子湖的铜锈环棱螺（Bellamyaaeruginosa）、长角涵螺（Alocinmalongicornis）、中华沼螺（Parafossarulussinensis）和耳萝卜螺（Radixauricularia）的壳形态性状和壳强度。4种螺壳形态可量性状之间以及壳形态可量性状与壳强度之间均呈显著的正相关，且存在明显的种问差异。探讨了螺类形态和壳强度与反捕食功能的关系。

英文摘要：

The morphometric characteristics and shell strength of Bellamya aeruginosa, Alocinma longicornis, Parafossarulus sinensis, Radix auricularia collected from the Liangzi lake, Hubei in China were measured. For all of the four gastropod species, there were pos- itive relationships among morphology parameters, as well as between each of morphology parameters and shell strength. There were in- terspecific difference in morphology parameters and shell strength. In addition, the effects of morphology and shell strength on the anti- predation abilities of gastropods were discussed.
