Varadero tadpoles metamorphosing

[John]

"It's morphin' time"....

This tadpole is the first offspring of this pair of "Varadero" race Ranitmeya imitator frogs.

This first photo was taken in the terrarium on June 29th. The tadpole is in a white film canister attached to the side of the terrarium with a suction cup:



This was taken on the night of July 7th 2010 in a small deli cup (Click the photo to enlarge):



You can see the colors of the frog coming in - even the legs are starting to get a little. I'll admit I'm quite worried about this tadpole because, being the first, it's the most likely to have Spindly Leg Syndrome (SLS), a malformation of the front limbs caused by a nutritional deficiency in young dart frog parents, often seen in their first few tadpoles. Keep your fingers crossed.

I'll keep you updated.

Very nice photo's John, The colouring is really prominent. I can see the arms are going to pop out soon. I hope you are worrying for nothing.

[John]

For comparison, here's that last photo again:



And now the same tadpole 48 hours later (taken just a few minutes ago):

[Ebony]

Looks to me like the arms and legs have grown significantly. It might be the photo but the colouring seems brighter too. Looking pretty positive I think. Mind you, that's going by what frogs I breed. How long does it take for these tadpoles to morph?

[John]

Yes, the colors are starting to come through now, definitely - the blue on the legs is more noticeable. The front right arm is bigger too. They take a while to metamorphose. He will probably pop the legs in the next 48 hours, then it'll be 4 more days or so I think.

[Kurt]

Very cool.

[John]

Now, 24 hours later:



There are quite a few subtle differences, such as the coloration on the legs becoming bolder, the body coloration becoming more clearly defined, the bulge around the right front leg is larger and the eyes are starting to bulge out (compare to previous photo).

2 days later (today) - click the photo for a larger version:



The arms broke through the skin in the last 18 hours or so and the froglet is breathing air. The colors are much better defined and the froglet is developing the classic 2-piece "mustache" characteristic of the species (though the froglet's mother lacks these markings).

[Kurt]

Its amazing that the color is so defined and vivid at this stage of development. Red-eyes at this stage are brown and drab.

[Jace]

The colouring is absolutely amazing. How long until you know about SLS? Is there any way to treat it if the froglet does have it?

[Ebony]

Looks beautiful John. I would also like to know about Jace's questions.

[John]

SLS is easy to see once the legs pop - this frog is fine. It can't be treated though. The smaller froglet here has SLS:

[John]

24 hours after last photo, here are three more:

[Jace]

They truly are beautiful, John. I can definitely see the difference between the healthy frogs and the one that has SLS. Is there anyway the froglet can survive with this condition? I'm keeping my fingers crossed that the rest of your tadpole develop normally.

[John]

Is there anyway the froglet can survive with this condition?

The problem is that they can't hold their body up correctly so they can't feed and the whole thing stresses them out because they know something's not right. Those that can't hold themselves up are done for.

I'm keeping my fingers crossed that the rest of your tadpole develop normally.

Thanks. Going on my own experience and what others have told me, SLS is pretty rare in R. imitator in comparison to other dart frogs, so I think if the first one is fine then the rest should be alright too.

I'm going to take more photos tonight - just looking at him in his canister I can see right away that his tail has decreased greatly in size over night and he's looking much more frog-like.

Oh WOW.
Gorgeous colouring; truly stunning.
Looks ike he's doing very well(:
Congratulations!

[Jace]

Will these new froglets eventually join your breeding program? Compared to American Bullfrog tadpoles, these guys seem to morph overnight! I can't wait to see more pictures. Thanks for sharing all of this with us.

[Ebony]

Yes John, thanks for sharing the process with us. They look beautiful and im still amazed on how their colouring is so apparent during metamorphosis.

[John]

If you think that color is early, look at the tadpole photo from Phil Tan of a Ranitomeya lamasi tadpole - note it has no legs so it's relatively young.

[Ebony]

Yes, they are really striking, I guess it must be easy to identify these guy's . I get blown away by the colouring of the frogs you can keep in your side of the world so for me to get the opportunity to see this is awesome. Thanks
