Something fishy

Underwater Times reports that scientists in Norway have dscovered a fish that can hold its breath under water. No, really.

The researchers have found that this extraordinary fish can change the structure of its gills to avoid becoming anoxic. In addition its blood has a much higher affinity for oxygen than any other vertebrate, and it makes tranquilizers and produces alcohol when oxygen supplies are limited. These mechanisms allow the fish to survive for days or even months without oxygen depending on the temperature, whilst still maintaining physical activity.

Alcohol and tranquilizers?!
