A sudden drop in temperature in northern Norway froze a school of fish solid as they tried to escape en masse from a bay.
Ingolf Kristiansen was out for a walk with Anton, his miniature schnauzer, when he came across the school of saithe, a type of fish belonging to the cod family, frozen beneath the ice.
"I've never seen anything like it. It has not happened before here as far as I know," he said.
"A temperature of minus 7.8 degrees, combined with an east wind, made the bay freeze in a very short time. The saithe had been chased to the shore by cormorants, and apparently were not able to get out to the open sea again."
