Jawfish, Indo., unid.ed 2/26/09 Hi all. Have learned much by reading through the website. The Bob's book was incredibly informing too. I was looking through you FAQs on Jawfish because i recently purchased one. My question is what can you tell me about so called Bali tiger jaws or tiger jaws, and gold specs jaws. I looked at the pictures in the identification section and they both look the same to me. <There are a few Opistognathids from the area as yet unidentified by/to science...> the jaws i purchased was sold as a tiger jaw but it does have goldish orange crescents above its eyes with a yellow down its dorsal fin and around its tail, as well as "tiger" striping down its sides. much thanks, Jonathan <Mmm, do see Fishbase.org re the family... Show all species... for the pix they have, species... I have only seen these Jaws occasionally in the trade here in the West... the last few years. Are hardy, beautiful... Jumpers! Bob Fenner>
Indescribable.. I mean Undescribed Jawfish...? Hello! I recently purchased a Jawfish that was labeled a Black Cap Jawfish, however, after searching your site, I see it labeled as a U1 undescribed Jawfish. Has this fish been IDd yet? Thank you, Jim <Mmm, maybe... I do recall seeing some that had been recently described. Maybe give a read over on fishbase.org on the family Opistognathidae... Bob Fenner> <<May be Opistognathus randalli. RMF>> Re: Jawfish Thanks for the response Bob! I checked that site and although it turned up loads of info, I didn't see anything on this particular Jawfish, unless I missed it, but I don't think so. I more curious now than ever! Any more info/leads you can provide would be greatly appreciated... Jim <Mmm, none other than Dr. Jack Randall has stated to me that he has more than a dozen undescribed species of these fishes... from the tropical Indo-Pacific... You might want to email him with pix... Bob Fenner> Re: Jawfishes ID Jim: The person to contact about Jawfishes is Dr. William F. Smith-Vaniz. He's the one who has many new species to described (and has been sitting on them far too long). His e-mail: Bill_Smith-Vaniz@usgs.gov <Thanks much Jack, mahalo, Bob Fenner over in Holualoa, mauka of Kona...> New Jawfish HELP 7/20/05 I just picked up a new Jawfish. The
LFS identified it as a Yellow Jawfish, however, after looking at your
site, it is described as "Opistognathus sp. U1" an
unidentified species. It looks just like the picture to the far right
of your description. The LFS had it in a tank with triggers and
aggressive fish. I have an aggressive tank, and they said it would be
fine. The LFS had the fish for about a month and it was doing well and
eating. It had built a burrow and looked very feisty. Has anything else
been discovered about this fish? I have a Huma Trigger, a Koran Angel,
a Yellow Tang, Snowflake Eel, Lionfish, and a Possum Wrasse in my tank.
Was I given the wrong advice? Indo Pix of the day, week, life (Identifications... this time Opistognathid U1) Lovely new pics. Are you sure your "Opistognathus sp." isn't indeed; "Opistognathus macrognathos" the banded Jawfish? http://filaman.uni-kiel.de/Photos/PicturesSummary.cfm?StartRow=1&ID=3686&what=species <... absolutely sure... the one pictured is also found on Fishbase as the species you mention: http://www.fishbase.org/Summary/SpeciesSummary.cfm?ID=3686&genusname= Opistognathus&speciesname=macrognathos along with a pic by myself... But the species (O. macrognathos) is found in the tropical West Atlantic... the pix I sent as unknown species I shot (for sure) a couple weeks back in N. Sulawesi. I have a bunch of "unknown" pix... and appreciate any help ad identifying them... Bob Fenner> Jawfish Hi Guys. My local FS here in the UK has just received a delivery of 6 of these beauties.......... <Agreed. This is a neat species.> "Opistognathus sp. U1. One of many as-yet undescribed Jawfish species. Dr. Randall (pers. corr.) told me once that he had backlogged at least a dozen or so in this family... let's hope he gets around to them soon. N. Sulawesi pix. OR Opistognathus sp. Gold Specs Jawfish. Mabul Malaysia. A male with a mouthful of eggs." Difficult to ID as the ones they have in have similar body markings but totally black heads with bright orange eyes. <Mmm, I wrote the above text and took the pix... as far as I know this species is still unidentified... What else can I add? Let's see, for the family they're quite outgoing, and don't seem to get any larger (have seen a couple dozen specimens)> We get very very few Jawfish into the UK and they are always expensive. I am taking a pair (can you ID male /female ??) for my system as first fish in. <Have seen males with eggs in mouth... but no discernible external differences I'm aware of between sexes> I have mixed substrate (aragonite, course grain and rubble) to a depth of 4"...I assume that would be ok. <Sounds good> Notice on WWM site that this species has very little information. can you give me a pointer to any other sites that might have or is this a relatively newish !! species. <Would have to look the same as you> Look forward to your prompt reply. Steve. Tope <Keep good notes, and an open eye for literature... and consider writing an article and more re your experiences. Bob Fenner> |
