Does it say anywhere how this is different from bluefin tuna which are also warm blooded? I think there's a few other large fish or sharks that are as well.

it talked about special functioning gills rewarming cooler blood with warmer blood

i did not see any comparison to tuna

I don't understand. Moonfish are not a new discovery. Is this particular fish different from the species or did they just figure out it was warm blooded?
