Abstract
Three species of Antarctic fishes which live in constantly near-freezing waters have a markedly low upper-lethal temperature of 6 degrees C ; this is the lowest upper-lethal temperature reported for any organism. The fishes survive supercooling to -2.5 degrees C. Data on brain metabolism in vitro support the hypothesis that the central nervous system is a primary site of thermal injury.
摘要
生活在持续接近冰点水温中的三种南极鱼类，其明显具有较低的致死温度上限，为6摄氏度；这是所报道的任何生物体中最低的致死温度上限。这些鱼类能在过冷至零下2.5摄氏度的情况下存活。体外脑代谢数据支持了中枢神经系统是热损伤主要部位这一假说。
