"In 2015, Lampris guttatus was discovered to have near whole body endothermy, where the entire core of the body is maintained at around 5 °C above the surrounding water. This is unique among fish as most fish are entirely cold blooded or are only capable of warming some parts of their bodies." (Wikipedia).......very interesting

That is an Opa. I've seen them caught on tuna charters. They fight like a giant piece of plywood. They are also delicious.

Yep, "Opah" if you want to get picky with spelling https://en.wikipedia.org/wiki/Opah

I find it fascinating that they can (somewhat) control body temp, instead of being truly cold-blooded, the only fish to do so, according to the link

Didn't know they were tasty, either, that's a lot of meat...

It's an open water oceanic fish. There's a few different types of them.

Some sharks have warm blood. The great white in particular has warmer blood than the surrounding water.
