Pretty sure I recently learned that fish actually mostly stick to shores and there's little to no migration across open ocean, so they might actually draw that very differently! It was an article about evolution or biodiversity and coastlines, and the article described how genes are transmitted globally despite having separate continents (iirc the waters are shallow enough near the north pole and around oceania to form one long line along all shores), but I can't remember it well enough to find it again. Tried checking it elsewhere but all the relevant-sounding Wikipedia articles don't seem to talk about the ratio of deep sea animals to near-shore animals. Can anyone else confirm or refute this?
Oh crap, thanks for letting me know. Didn't see it in time for the edit window though :( if only HN had notifications or just lets you edit, y'know, your own posts
