Nature and its wonders can never be understood by man. A recent example of this has emerged in the form of a fish.

Fishes are said to be cold blooded and contrasting this, a warm blooded Opah fish has been discovered.

According to the reports of a Science journal, the Opah fish which is also known as the moonfish is the first ever warm blooded fish found by scientists.

A team of researchers from National Oceanic and Atmospheric Administration's (NOAA) Southwest Fisheries Science Center monitored the fish’s body temperature and noted that Opah fish’s body temperature was five degrees Celsius warmer than the water at cold depth in which the fish was swimming.

It has been revealed that the pectoral muscles of the fish generate much of the heat in its body. The arrangement of blood vessels in the gills of Opah is such that the cold blood coming in from gills is warmed by warm blood being carried towards the gills, researchers mentioned.

Having warm blood helps the Opah in predation.
