Mr. Lipps is hopeful that the torpor-like state that hellbenders are thought to enter during winter will help them survive.

利普斯希望大鲵在冬天进入的类似麻木状态，这能帮助它们生存下来。

Ecologically, one concern is for hellbenders, a prehistoric-looking aquatic salamander that can reach two feet long and is endangered in Ohio.

从生态学的角度来看，人们担心的是美洲大鲵，这是一种史前模样的水生蝾螈，身长可达两英尺，在俄亥俄州已濒临灭绝。

One site, where about 250 hellbenders have been released since 2014, is between areas where dead fish have been found since the derailment, said Gregory Lipps, a herpetologist at the Ohio State University who leads the effort.

俄亥俄州立大学爬虫学家、负责这项工作的格雷戈里·利普斯说，其中一个地点位于事故发生后发现死鱼的地区之间，那里自2014年以来有约250条大鲵被放生。
