Scientists find hibernating fish in Antarctic
LONDON (Reuters) - Scientists have found an Antarctic fish that hibernates to conserve energy during the long southern winters.
Scientists have discovered an Antarctic fish species that adopts a winter survival strategy similar to hibernation। Scientists from British Antarctic Survey (BAS) and the University of Birmingham reveal, for the first time, that the Antarctic 'cod' Notothenia coriiceps effectively 'puts itself on ice' to survive the long Antarctic winter.
The study showed that the fish activate 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 long, Antarctic 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. Scientists already know that Antarctic fish have very low metabolic rates and blood 'antifreeze' proteins that allow them to live in near-freezing waters. This study demonstrates that Antarctic fish - which already live in the 'slow lane' with extremely low rates of growth, metabolism and swimming activity - can in fact further depress these metabolic processes in winter.
Lead author Dr Hamish Campbell, formerly at the University of Birmingham, UK but now at University of Queensland, Australia said, "Hibernation is a pretty complex subject. Fish are generally incapable of suppressing their metabolic rate independently of temperature. Therefore, winter dormancy in fish is typically directly proportional to decreasing water temperatures. The interesting thing about these Antarctic cod is that their metabolic rates are reduced in winter even though the seawater temperature doesn't decrease much. It seems unlikely that the small winter reductions in water temperature that do occur are causing the measured decrease in metabolism. However, there are big seasonal changes in light levels, with 24 hour light during summer followed by months of winter darkness -- so the decrease in light during winter may be driving the reduction in metabolic rates."
Dr Keiron Fraser from BAS says, "This is our first insight into how these fish live in winter. We have for the first time in the Antarctic, used cutting edge technologies combining tracking of free swimming fish in the wild and heart rate monitors to allow us to investigate just how these animals cope in winter with living in near freezing water and almost complete darkness for months on end. It appears they utilise the short Antarctic summers to gain sufficient energy from feeding to tide them over in winter. The hibernation-like state they enter in winter is presumably a mechanism for reducing their energy requirements to the bare minimum. The interesting question we still have to answer is why these fish greatly reduce feeding in winter when food is still available."
Why these fish chose to adopt this hibernation-like strategy during winter is currently unclear, but it presumably provides energetic benefits. The traditional views of hibernation are being challenged constantly. This study introduces a new group of animals that appear to utilise a hibernation-like strategy that allows them to survive during the long winters in one of the harshest environments on Earth.

About Antarctic cod
The 'Antarctic Cod' (Notothenia coriiceps) became isolated from its warmer water cousins around 30 million years ago when the Antarctic circumpolar current was formed. The olive-coloured fish has a broad head and a narrow body. Whilst scientists know that it has a glycoprotein antifreeze in its blood and it maintains a very low heart rate of less than 10 beats per minute, very little is known about its behaviour or how it evolved to live in Antarctica's extreme environment.

I'de rather it be CloverField than gas, I really would. But Im guessing there are alot of possibilities to what it really could be.
