I have also seen these in other places in Indonesia.
Edit: for example, at Komodo:

it's rather difficult to identify the crustacean group on these photos, I have never seen these critters before
I would say it's an ISOPOD rather than a larval crab, an amphipod or a copepod, but I would need a hyper-macro for confirmation
I am a bit puzzled by the strange (? posterior) orange expansions
hope we can soon elucidate this problem
HAPPY NEW YEAR !

Assuming that the anterior appendages are antennae and not stalked eyes then it might be worth looking at the ISOPOD genus Santia?
Which is a rather Christmassy answer until someone comes up with something better!

I don't think it's Santia, at least the Californian Santia hirsuta and a Caribbean species look quite different
these guys look more like this one from Guana (British Virgin Is):
it's a very nice site for small Caribbean critters by the way, but most species are not yet identified (we're working on it)
I will ask a Japanese colleague working on marine isopods Santia, Munnidae etc. (maybe he also knows the tiny spider-looking and the red guys from Jervis Bay)

Can you post some words on your experience with it?

I'm pretty sure craig got shots of something similar in Lembeh or Komodo.
Hopefully we can comply and turn them into kodak moments in September.

You normally would have osmeone that knew on most dive boats I have been on ..
In my now half educated referenced brain I would put money down that it is actually a tiny giraffe found only in wakatobi and is highly endangered and should not be photographed using flash photography as this eliminates the sexual reproductive capabilities of these fine fine subaquatic pygmy giraffes
ok ok .. seriously I am going for Amphipods from that last photo .. the previous one was hard to decide on but now I am definately Amphipods although I cant find the website I saw the similar photo on . I just searched using google
although i did search all of the suggested creature to make my decision .. I may just have chosen the wrong one .. I'll inform later when i get home form work .. if you see this post edited .. it's cause i cheated !

Good Job David, but are you sure that's not a dogs back

Thanks Jimbo, fame at last eh!

hmmm ... I am still not convinced that they are amphipods, it's possibvle though
amphipods usually have large coxal plates invisible here due to this strange brown-orange substance covering the body, which unfortunately also hides the segmentation pattern on the abdomen
also, critters on the third photo are fairly broad, amphipods are usually laterally compressed ..
I sent this photo to my colleagues yesterday, let's see what they say
by the way, I don't want to be a "moray eel" (see on the left) .. but .. let me think about my character .. a "jaw fish" !!!

you are right, they are isopods. To me they appear to be a species of
Santiidae, the uropods being held up in the characteristic santiid fashion.
What is more unusual is the detrital (or other) covering of all the dorsal
These Asellota are so covered with material that I cannot be certain. They are not, however, Munnidae because they have visible uropods. Specimens? Without inspecting them, I can't say for sure.
well, for the moment the consensus is Isopoda - Asellota, maybe Santiidae (but probably not genus Santia, see my message above), certainly not Amphipoda

two more replies:
Yes I thought that they could be Santiidae from the shape of the uropods, but they could also be one of the other little familes that accumulate crud like that, as well as some things we haven't described yet. I didn't want to say anything definite without more data. I would like to have specimens, if they can be gotten.
this one is from a Japanese specialist who described a new species in the genus Santia:
Thank you for your mail. They are isopods of Santiidae, maybe a species of the genus Santia. I could observed some essential characters of the genus from photos, these have long antenna 2 and robust uropods composed of protopod, exopod and endopod (In munnids and paramunnids uropods are very small, and in paramunnids antenna 2 is short.). Living santids look like red due to a large number of tiny red algae growing on the surface of body and appendages.
my compliments to Alex Mustard - he suggested first that it could be Santia !!!
although it's still not confirmed ...
my link to an unidentified isopod from Guana (BVI) - judging from these descriptions this isopod could be a Santia, too !!

the debate continues, although I am not sure that somebody really cares now ... I guess my monologue becomes quite boring ...
anyway, regarding the genus Santia my colleague George Wilson (Australian Musuem) replied:
I wouldn't think that genus name. I am only willing to suggest that they might be the family Santiidae, with the provisio that other families could have the same appearance (e.g., Janiridae, Pleurocopidae, or even a shallow water Dendrotiidae). Or even something that no one has described yet ...
the guy from Japan believes it's Santia, as is the isopod on my previous link, I sent him that photo and he replied:
Yes, it is a species of Santia, too. Only one species of the genus, Santia milleri (Menzies and Glynn, 1968) is known from Caribbean Sea up to now. To judge from the photo, I think it is just the species. But, there is a possibility of new to science
HEY GUYS !!! DON'T SLEEP !!! TRY TO CATCH A FEW OF THESE CRITTERS !
