I have been wondering about Polycheles typhlops. I would have nominated it myself for DYK, if only I had been able to find a good hook. It really is a fascinating animal, but there's nothing (cited) in the text that jumped out as instantly notable. I agree that the "two species" claim is false, and that the reference proves it (planktonic larvae can be easier to find than animals living on the sea floor at depths of >2000 m, so it's not that surprising that species have been missed). I wasn't sure if someone else would find a good way of re-wording it and save the DYK entry; I certainly couldn't think of one, but I didn't vote it down just in case. That DOI is an odd thing indeed. Springer Link definitely gives the same DOI I put in the article, but dx.doi.org doesn't recognise it. It's not even as if it's a very new article that hasn't made it into the DOI database yet. I have added a link directly to the journal article; I am wary of removing the DOI, because it *ought* to be right, although I doubt that it will come back to life. At least this way, people will find the article if they need to. Oh, and thanks for rescuing the conservation status of the Steppe Field Mouse. I checked to see if Apodemus witherbyi was listed, and found nothing.
