I need your help - again!

[Gonodactylus]

We are finishing up a study on sexual dimorphism in Odontodactylus scyllarus (peacock) signaling and I need a juvenile (under 80 mm, 3.5 inch) male. I thought I had one, but when we went to work with it, the animal was a female. Either I missed the call, someone switched labels, or it changed sex. (Seriously, has anyone had a stomatopod change sex on them? I suspected this once before with P. ciliata.)

Anyway, if anyone sees a small male for sale or has one they would like to trade or sell, I would appreciate a pm. I still have another copy of "Fastest Claw" I can offer as a finders fee.

And as always, I'm always on the look-out for an Odontodactylus cultrifer.

Are you offering one of almost any specimen you have in your lab as a reward too? I believed you did thatone for a cultrifer. Don't have one, just curious....

 

[Gonodactylus]

I don't think I have anything right now that people would want except for a lot of N. wennerae, G. chiragra and O. havanensis. Our Lysios are not on the table. As I have said before, I can't sell our research animals, but a liberal interpretation of the law would allow me to trade.

On the other hand, if someone wanted juvenile octopus (bimacs and O. mercatoris), I might consider it.

That reminds me of a question I had. I was wonderingwhat you do with reasearch specimens when your research is completed? Do you keep them in te lab, release them? Give them to interested tudents or bring them home yourself? I don't mean to intrude, but it is just something I have wondered about Dr. Roys mysteriou lab located deep inside of Berkeley. Will keep a look out for both juvie peacocks and O. cultrifer.

Let's keep Dr. Roy's thread on track

Feel free to start a new one related to other lab questions.

Thanks.

Ok, I just wanted to say I am sorry. Sometimes I have trouble keeping myself in check and get sidetracked. Also, check out saltwaterfish.com They sell peacocks supposedly at 3". You could probably email them and ask for an inividual of a smaller size and ask them to sex it. I've never personally dealt with them, but it couldn't hurt to try. Also, When I first got my P. ciliata I sexed it as a male. I have been having trouble seeing the penes. I swear it was a male when I got it. I can't be positive unless I capture it to get a closer look, but I am having trouble seeing them.

I just got a fairly small O.Scylarrus I don't know the sex though. I can try to catch him to get a closer look, but so far he has stayed in the rocks and has not ventured far in his side of the aquarium. Also about SWF.com they have listend on there site Peacock, but the picture is NOT one. Just thought I'd say that.

Still haven't gotten a close enough look to tell the sex. Wish there was an easier way to tell...

 

[Diet Plain]

It is a male. But I think he may be a little too large for what you wanted. He is approx. 3.75 inches. Don't know if that little bit actually makes a difference.

 

[Gonodactylus]

That is on the large side for our needs. The animal is probably just becoming sexually mature. I assume that the uropods spines ( the seven or eight thick red spines on the outside margin of the uropods) are still red. In fully mature males they turn whitish. If you have a polaroid filter (photographic filter or even an old pair of sunglasses), try looking at the uropod spines while rotating the filter. In immature males there should be no change but in mature males the spines will switch between red and white.

Thanks.

Wish I did, I heard about their "signals" they used but never got a chance to see it for myself. Goodluck on the research.
