To understand how the land snail fauna is related with the divergence of morphology related to snail feeding (macrocephalism vs. stenocephalism) in the subtribe Carabina, we conducted field studies in China, Korea, Armenia, and Morocco. In the inland region of China, especially, diverse snail-feeding Carabina species and land snails occur. Macrocephalic Carabina species occur in habitats harboring small-sized bradybaenid snails abundantly. In habitats where both macro- and stenocephalic Carabina species occur, the shell morphology of bradybaenid snails was markedly diversified, suggesting an adaptive radiation due to strong predation pressure from snail-feeding predators.

为了了解与蜗牛喂养有关的形态差异（大脑剂vs. stenocephalism）的陆地蜗牛动物之间的关系，我们在中国，韩国，亚美尼亚和摩洛哥进行了实地研究。在中国的内陆地区，尤其是在多种蜗牛喂的卡拉比纳物种和土地蜗牛。脑头甲虫物种出现在具有小型Bradybaenid蜗牛的栖息地中。在发生宏观和脑脑carabina物种的栖息地中，Bradybaenid蜗牛的壳形态显着多样化，这表明由于蜗牛喂养捕食者的强捕食压力强，因此具有适应性辐射。
