Paramesotriton laoensis breeding

[jef]

looking great paul,keep up the good work!

Hi,

here you see the difference between P.deloustali (left) and P. laoensis (right).
Two weeks old larvae:

The P.deloustali I got as eggs from an other urodela friend.
The deloustali have yellow parts on the eyes, gills, tail and mouth; the laoensis not.

Greetings Paul

Hello Tim ,
The register is International.
Best Wishes,
Gustavo.

That's really interesting Paul, to my knowledge, all other Paramesotriton sp. larvae have yellow colours on their body, even P. caudopunctatus. Very strange that these are all-black!

 

[jennifer]

Yes, P. caudopunctatus do have the usual yellow eyes/nose. I agree, very interesting that these do not.

Dear caudates colleagues :

After several conversations with other collegues we have concluded on the need of creating a new register for Paramesotriton deloustali and Paramesotriton laoensis within the DGHT/URODELA-AG.
I have the pleasure to inform you that I have the honour of being the Godfather of both registries.
If you have any suggestion please don’t hesitate to contact me;

Best wishes,
Gustavo Espallargas

Hi,

they are eating well!

3 weeks!

Hi,
I found an interesting difference in the behaviour between P. deloustali and P. laoensis larvae.

The P deloustali nearly always sit in the Javamoos:

The P. laoensis nearly only on the ground:

Dear caudates colleagues,

is it really true, that only P. laoensis’ larvae are all black and all other Paramesotriton species’ larvae have yellow elements?

I have read that Pachytriton C larvae look like Paramesotriton larvae except from the yellow parts. So another questions is, are all Pachytriton larvae completely black?

And if it’s so, isn’t it another hint, additional to the reduced tongue structure, that P. laoensis is perhaps relatively close related to Pachytriton…

That’s very interesting, isn’t it?!!


I hope you’re as much amazed as I was, seeing Paul’s laoensis larvae!!! Great job, Paul!

 

[paul]

Hi Timo,

I think, it is one more hint, that P.laoensis is different to the other Paramesotriton.

But comparing my laoensis with Pachytriton, I can not believe that it is more close to this genus.

This larvae are less more than 2 months:

Paramesotriton loaoensis:

Very cool. Larvae from this genus are one of my favorites, I love the pitch black body and the yellow gills!! Some of the pics would be great on CC in the species section, there is no larvae pics of this species there.

Hello!

Today I saw, that there is the first sign of the typical P. laoensis coloration:

3 months, nearly 4 cm, 300 mg!

Perhaps the beginning of metamorphosis!

Paul

 

[ryan]

I can't wait for metamorphosis, it looks like you've done a great job of raising these youngsters, good luck in the long run.

How many do you currently have?

 

[paul]

Thanks Ryan,

I have nine in this age, but a lot of younger larvae.

Paul

 

[paul]

The first

Fantastic, Paul....good luck with the next stage.
Have you thought about writing a paper with all your observations on this?...i'd be really interested if you could give exact details. I had my males tail waving, chasing females and even dropping spermatophores but all this activity suddenly stopped as quick as it had started.

Again, congratulations! this is a great achievement

 

[paul]

Thanks, Andy!
Yes, together with Gustavo I make an article about breeding of Paramesotriton deloustali and laoensis.
And of course I'll give a presentation in Gersfeld.
