photographed at night ? looks indeed like the night colour pattern of Pontonides ankeri (probably synonym of P. loloata)

perhaps a species of Thor, some of them like hanging out around anemones

Hey guys ! we (a colleague of mine in the UK and myself) just launched the preparation of a long awaited key to all genera of shrimp-like decapod crustaceans (Procarididea, Caridea, Stenopodidae, Dendrobranchiata) of the tropical and subtropical Western Atlantic, followed by a similar key to the genera of the Eastern Atlantic and later also the Eastern Pacific ... Indo-West Pacific is planned down the line, this could be a project for 2013-2014 the key itself will be pretty technical and illustrated with some line drawings and BW photos (taken under a microsocpe or a dissecting scope) to show at least some important distinguishing characters in addition, to make the paper more colourful and "appetising", for each family we want to provide 1 colour plate showing a selection of genera I have a lot of photos of various shrimps, mainly from Panama and Honduras, therefore, we will be quite happy to include photos from other areas (West Atlantic from North Carolina to NE Brazil, Caribbean, Gulf of Mexico, + any locality in the subtropical and tropical East Atlantic and East Pacific) to increase taxonomic and geographic coverage, and also to show both in situ and lab shots so if there are some shrimp lovers on Wetpixel who want to contribute with nice photos, please let me know, here is my email artour_a(AT)yahoo.com also, maybe you know somebody who has photos of deep-water and pelagic shrimps from the area, these are pretty scarce thanks Art

Hi folks a colleague of mine is searching for photos of aplacophorans - worm-like mollusks, without shell - for a book on invertebrate phyla .. can be either caudofaveates or solenogastrids most species are small and in deep water, but there are some shallow-water representatives if you have some pictures, please contact me at artour_a*yahoo.com (replace * with @) thanks Art

Latreutes sp I think, perhaps L. porcinus

it's a new hippolytid genus & species being described by Okuno & Marin Art

hey folks here is something for the shrimp (and not only shrimp) lovers : a feather shrimp (Microprosthema plumicorne, Spongicolidae) from French Polynesia http://www.flickr.com/photos/artour_a/4121188823/sizes/o/ enjoy ! Art

it is P. cf. soror and yes, I believe P. soror is a species complex too many colour morphs, different hosts ..

well, Ivan says: Periclimenes commensalis, typical colour ...

Leslie: I know it was SDG who told you that, but neither of us can do much with photo alone .. also, we may deal with 2 species here, one hippolytid and one pontoniine, SDG may be right, one of them may be Dasycaris, but this one I am really not sure .. I hope we'll get a couple of different aspects, I need at least one where you can see the position of the larger pair of chelipeds ;o) A

the genus Saron needs a complete revision the S. marmoratus and S. neglectus complexes both need redefinitions VERY UNFORTUNATELY, specimens are not collected, only photographed that's why it will probably take another 10 years or so to describe these guys (probably >7 species) I have "working names" for the two Saron species shown here, but no specimens .. Art

tufts on the carapace and abdomen are typical to Hippolyte spp (Hippolytidae s. str.) in addition, the P1 seem to enlarged, not the P2, as in the Pontoniinae need slightly higher resolution to see first 2 legs and the rostrum .. Art

quite disappointed that nobody replied (except for you Leslie !) nobody cares about my shrimp the one with golden spots is probably undescribed, and it's not sure that it is a Pontonides off to Peru in 10 days ! will explore the Amazon, have 3 weeks Art

ok ok ok P. ankeri (G) has 2 bands on the CARAPACE P. loloata (H) has only 1 I can send a complete pdf to anybody interested Art

Hi guys I know this forum may not be the best for this, as most of you don't collect animals, even for scientific purposes .. anyway, a colleague of mine is searching for specimens of whip and wire-coral associated shrimps, Pontonides spp, to determine whether Pontonides ankeri Marin, 2007 is the same as Pontonides loloata Bruce, 2005 morphological differences are minor, but the two species can be distinghuished by colour: P. loloata has one pale band crossing the carapace, while P. ankeri has two (see below) maybe somebody has photographs showing both forms on the same host, this would be at least very suspicious, indicating that the two species may be the same .. on the other hand, host partition is not uncommon, so specimens are always better ! also, DNA analyses may be needed for genetic confirmation you can post your replies here or email me: artour_a(AT)yahoo.com cheers Art
