That's right. He's the King of the Herrings.
So this of course intrigued me, and prompted me to look further in to this species. As it turns out, they don't seem to be related to herrings at all. Best I can tell, the closest taxonomic level they share is that of class, which encompasses every single ray-finned fish. Does the moniker mean that they lord over the herring with their vast size and appetite? Most likely not, as Opah eat mostly squid and krill, and the occasional small fish. Silly old book! Then again, they messed up the species name too, which they don't have much of an excuse for. Lampris guttatus has been called as such since 1788.

Opah are found in tropical and temperate oceans worldwide, and live at depths of between 100 and 400m. Opah are believed to be solitary, and they are not fished for commercially. They are occasionally caught as a byproduct of tuna fishing, and most of the Opah meat sold in the United States is from Hawaii.
There really isn't all that much else known about Opah. There is no indication that their population is threatened or in a decline.
I've never heard of this thing. I thought at first it was a gigantic relative of some of the really big tetras I've seen, but it turns out it's related to the even more gigantic oarfish. Fascinating stuff, nice find!
ReplyDeleteThanks :) I find a lot of really weird stuff paging through old zoology books. I'm really interested in actual Oarfish now, especially since I discovered there is an actual species commonly called "King of Harrings." Where are these names coming from?
