Scientists have decoded the secrets behind a goldfish's ability to survive in ice-covered lakes.

They've worked out how and why the fish turn lactic acid in their bodies into alcohol, as a means of staying alive.

Some goldfish were found to have levels well above legal drink-driving limits in many countries.

The researchers say the work may help with the study of some alcohol impacts in humans.

Scientists have known about the peculiar survival abilities of goldfish and their wild relatives, crucian carp, since the 1980s.
