Finally, a fish that never needs a heater!

[Ron]

"In a discovery that defies conventional biology, a big fish that lives deep in the Pacific Ocean has been found to be warm blooded, like humans, other mammals and birds.

Researchers from the National Oceanic and Atmospheric Administration (NOAA) determined that unlike other fish, opah generate heat as they swim and distribute the warmth throughout their entire disc-shaped bodies by special blood vessels."

Sea turtles do as well.

Good to see someone else interested in the science of things. I wasn't aware, but after some searching, it appears that Leatherbacks may be warm blooded. Are there any other sea turtles that I'm missing?

AFAIK...Tuna and Mackerel Sharks are warm blooded just like the Moonfish(Opah)...funny people have been eating Moonfish forever and now find out they're warm blooded?? That's science for ya.

I believe that the greens are as well.
