ABSTRACT On 8 May 2018 at 23:15 h physical contact was observed between an adult carnivorous land snail (Powelliphanta hochstetteri obscura) and an adult Maud Island frog (Leiopelma pakeka) on Te Pākeka/Maud Island, Marlborough Sounds, New Zealand. The land snail (40–45 mm diameter) was on its back with its foot under the frog (38.5 mm snout-vent length), raising the possibility that this was a predation attempt by the snail. Carnivorous endemic land snails are only known to consume a range of invertebrate species, especially earthworms. Our observation suggests that these snails might also opportunistically attempt to consume small ground vertebrates, although definitive evidence is required.

本地青蛙 (Leiopelma pakeka) 和食肉陆生蜗牛 (Powelliphanta hochstetteri obscura) 之间的身体接触：发生了什么？

摘要 2018 年 5 月 8 日 23 点 15 分，在新西兰马尔堡峡湾的 Te Pākeka/Maud 岛上观察到一只成年食肉蜗牛 (Powelliphanta hochstetteri obscura) 和一只成年 Maud 岛蛙 (Leiopelma pakeka) 之间的身体接触。陆地蜗牛（直径 40-45 毫米）仰卧，脚在青蛙下方（38.5 毫米鼻孔长度），这增加了蜗牛企图捕食的可能性。只知道肉食性地方蜗牛会吃掉一系列无脊椎动物，尤其是蚯蚓。我们的观察表明，这些蜗牛也可能会投机取巧地尝试食用小型地面脊椎动物，尽管需要明确的证据。
