  1. Gerry Allen has looked at this forum topic and commented by email:-


    "This is an undescribed species that is similar to Discordipinna, but may in fact belong to a new genus. A group of Japanese researchers are working on the description and I would expect this to be published in the near future. It is currently known from Indonesia (Lembeh and Raja Ampats), Papua New Guinea (Milne Bay), Fiji, and the Ryukyu Island of Japan. The species is featured in our recent 3-volume work on East Indian Reef fishes (page 912, Reef Fishes of the East Indies by Allen & Erdmann 2012).The fish in the book with the dorsal "spike" is most likely the male."


  2. Kaj, my images are of a pair in very close proximity, that seemed to be following each other around. There appeared to be no territorial aggression between the pair, so I assumed that they are male and female. If you look carefully at the dorsal markings you will see they are different. In my first image the dorsal and tail fins have a black margin which is not present in my second image nor Barb's images. Barb's images seem to have a black spot on the tail fin and two black spots on the second dorsal, which seems to match with my second image and the YouTube video.


    Bart, are you able to scan or photograph the "whiskered goby" (Discordipinna sp.) image from "Reef fishes of the East Indies" and post it here for comparison and comment?

  3. Kaj,


    I contacted Helen Larson by email about the photos I took at KBR in Dec 2012 and she replied:-

    "You have the mystery mudgoby. It does not yet have a name and I'm uncertain when it will! Dave Greenfield and I started to describe it some years ago and then learned that other people were working on it - it's a long and complex tale and the fish is still not named. I hope to meet up with some of the people involved in Okinawa and we can work out how to progress."

    So the best ID at the moment is the common name "Mini Mud-Goby" and there is a Youtube video of it






  4. Thanks Jim, Kaloplocamus peludo does look a good fit, certainly hairy enough too.


    Maybe Kaloplocamus maru as the body is browner and the description mentions the dark brown spots on the notum and gill branches. Though Richard Willan on Wetpixel questions if K. maru is the same species as K. peludo.

  5. Here's a couple of shots of a nudibranch from Manado, Indonesia.


    It's seems familiar to me, but I can't figure out what species or even genus this is.


    There seems to be a golden patch on the notum just in front of the cerata. Maybe that patch is a caruncle (like in Janolus) or maybe it's actually the rhinophores, because the white tentacles with black markings seem more like oral tentacles than rhinophores.

    Lastly, I've attached a large cropped photo of the head. Any ideas as to species?
