A Google image, for the record: In case I'm not the only person who reached her mid-forties having no idea that there even was such a thing. It turns out that sunfish, a.k.a. mora, are pretty common off Cape Ann. When we saw the one we saw, we had no idea. We even contacted a website that was tracking mora, to say where we'd seen it. I don't think it was well known even in marine biology that Cape Ann was a 'hotspot' -- apparently research into these fish is still very young.
