摘要

摘要据报道，巴塔哥尼亚两种成功入侵物种——欧洲青蟹Carcinus maenas（Linnaeus，1758）和具有潜在神经毒性的灰侧鳃海蛞蝓Pleurobranchaea maculata（Quoy&Gaimard，1832）——之间发生了一种意想不到的捕食者-猎物相互作用。在两个不同的场合，总共观察到四只螃蟹在田里捕食海蛞蝓。这些物种之间建立一种新的捕食者-猎物相互作用，可能会对它们在西南大西洋的潜在传播和入侵成功产生重大影响，同时也为了解目前尚未充分探索的关于吃海蛞蝓的问题做出了值得注意的贡献。

Unexpected meal: first record of predation upon a potentially neurotoxic sea slug by the European green crab Carcinus maenas

ABSTRACT An unexpected predator-prey interaction is reported between two successful invasive species in Patagonia, the European green crab Carcinus maenas (Linnaeus, 1758) and the potentially neurotoxic grey side-gilled sea slug Pleurobranchaea maculata (Quoy & Gaimard, 1832). On two different occasions, a total of four crabs were observed preying upon the sea slugs in the field. The establishment of a novel predator-prey interaction between these species can imply significant effects on their potential spread and invasive success along the South Western Atlantic, as well as it provides a noteworthy contribution towards the knowledge of the currently underexplored question related to what eats the sea slugs.

期刊介绍： Aims: The diversity of the fauna of the southern continents and oceans is of worldwide interest to researchers in universities, museums, and other centres. The New Zealand Journal of Zoology plays an important role in disseminating information on field-based, experimental, and theoretical research on the zoology of the region.
