Most crocodiles in Florida are tagged as hatchlings so biologists can easily recognize them, Hord said.

佛罗里达州的大部分鳄鱼在刚孵化出来时就被作了标记，所以生物学家能够很容易地认出他们，霍德说。

"They're just taped on temporarily," Hord said. "we just put the magnets on when they're captured and since they don't know where we take them, they're lost."

霍德表示，“这些磁铁都是暂时的，当我们捕捉鳄鱼时，将磁铁短暂地贴在鳄鱼头两侧，这样它们就无法辨别当地磁场，就会迷失方向。”
