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

然而，如果它的壶腹强的磁场过度刺激，鲨鱼就会排斥，而不是吸引。

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.

他提供的一种能性是， 大青鲨的大而尖的鼻子上有更多的 Lorenzini 壶腹，而不是黄貂鱼的较小、不那的壶腹。

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 壶腹的器官检测到这些，这些器官是散布在鼻子和嘴巴周围的充满果冻的受体，用于感知潜在猎物肌肉产生的电场。
