Deep-sea Opah are the first known warm-blooded fish that keep their internal organs whole above ambient temp, using counter-current heat-exchange. (Some tunas and sharks are semi-warm-blooded; can keep their swimming muscle temp slightly elevated).

Thanks for posting!
According to the article, Opah spend most of their time at depths of up to 1,300 ft, While I'm pretty sure I may never own a Saltwater tank. I am pretty certain I will never own one that deep... too much!

I found the article very interesting. We know so little about creatures of the deep. I was struck by the appearance of the fish too. I love the shape and colors. I enjoy reading about fish that I may I never have an opportunity to own. There are so many fascinating creatures. Thanks...Cool

The article was very interesting. It seems to me that Kroger has this fish in the fresh fish case. I asked the guy the other day and he said they do get it in, sometimes it's labeled moonfish. When I've seen it, it didn't look appetizing, I prefer really white, thick filets.

My question is, at the depths where it lives, how can they collect this fish for food?

I dont know the details of how they're fished, by line or by net, but never underestimate the commercial fishing industry -- they've got all sorts of gear for locating and harvesting enormous quantities of fish and crustaceans from all depths. It's become a technological (and marketing) arms race to see who can catch and sell previously unexploited species, as the traditional mass-harvested species are depleted.
