Temperature tolerance of some antarctic fishes

George N. Somero, Arhur L. DeVries

Research output: Contribution to journalArticlepeer-review


Three species of Antarctic fishes which live in constantly near-freezing waters have a markedly low upper-lethal temperature of 6°C; this is the lowest upper-lethal temperature reported for any organism. The fishes survive supercooling to -2.5°C. Data on brain metabolism in vitro support the hypothesis that the central nervous system is a primary site of thermal injury.
