Warm Blooded Fish

A species of fish that is warm blooded, has been found for the first time. This fish, the opah, who lives in oceans around the world, manages to keep its body a few degrees warmer than the surrounding water. This is similar to birds and mammals, preciously thought to be the only warm blooded living beings. The warmth of the opah's body makes it possible for it to swim faster, thus being a good hunter. I guess you can compare this to the warm blooded hunters like dogs and wolves. We are better at hunting, because we are warm blooded. Warmth is a good thing.
