Frostfish have been making an appearance on Caroline Bay in recent weeks.
At first glance the frostfish appears to be a thin-looking barracouta, but is much thinner than the barracouta, having a more laterally compressed body. It is also longer with an average specimen measuring up to 1.5 metres, the Fishing Mag website reports.
They are also known to be occasionally washed ashore on New Brighton Beach in Christchurch during the winter.
The species is found all around New Zealand but usually out in water between 200m and 500m deep.
