Scientists from Cambridge’s British Antarctic Survey (BAS) and the University of Birmingham have discovered an Antarctic fish species that adopts a winter survival strategy similar to hibernation.
Reporting in the online journal PLoS ONE, the team revealed for the first time, that the Antarctic ‘cod’ Notothenia coriiceps effectively ‘puts itself on ice’ to survive the long Antarctic winter, activating a seasonal ‘switch’ in ecological strategy – going from one that maximises feeding and growth in summer to another that minimises the energetic cost of living during the winter. The research demonstrates that at least some fish species can enter a dormant state, similar to hibernation that is not temperature driven and presumably provides seasonal energetic benefits.
