If, however, its ampullae are overstimulated by a strong enough field, a shark is repelled, rather than attracted.

然，如果它壶腹被足够强磁场过度刺激，鲨鱼就会被，不是被吸引。

One possibility he offers is that blue sharks have more ampullae of Lorenzini on their big, pointy noses than do stingrays on their smaller, less protuberant ones.

他提供一种能性是， 大青鲨大尖鼻子上有 Lorenzini 壶腹，不是黄貂鱼较小、不那么突出壶腹。

Elasmobranchs detect these via organs called the ampullae of Lorenzini, which are jelly-filled receptors scattered around their noses and mouths that serve to sense the electrical fields generated by potential prey's muscles.

Elasmobranchs 通过称为 Lorenzini 壶腹器官检测到这些，这些器官是散布在鼻子和嘴巴周围充满果冻受体，用于感知潜在猎物肌肉产生电场。
