Pics of 'Hybrid' Dart Frogs
#1
Web hosting by Ed. K. Frogs were not animals that produced under his care. Someone else 'engineered' them.

They definitely aren't much to look at, but look at that second picture how big that cross looks compared to any normal auratus. It's like King Kong...

As I anticipated it is encouraging mixing....
As far as the "sterile" comment I think that is incorrect.

I believe you're correct Beth. That's where the danger comes in, releasing hybrids capaeable of reproducing, into the hobby. Unlike most hybrids, I believe I've heard that dart frogs are not sterile.

Sterility in hybrids is often the result of different chromosome counts in the parents. If species A with a diploid (2n) number of 32 chromosomes (n=16) breeds with species B with a diploid number of 30 chromosome (n=15), then the resulting F1 generation will have a 2n of 31 (16 from A and 15 from B). That means that one chromosome doesn't pair which leads to issues in meiosis and sterility.

If, however, species a has A 2n=34 instead of 32 (n=17), then there's a chance offspring from A x B can be fertile because the F1 would have a chromosome count of 32, and the chromosomes can pair normally. I have no idea of the chromosome counts of any dendrobatids to say whether they'd be sterile or not.

Obviously the two tincs will have the same chromosome count.
It's been awhile since I read up on the whether the auratus and leucs have the same count as the tincs, but I seem to remember that they do in fact have the same count.
Darts with parasites are analogous to mixed tanks, there are no known benefits to the frogs with either.


If tone is more important to you than content, you are at the wrong place.

I'm pretty sure I saw a pic of a leucomelas X auratus hybrid.

I really don't think that the pics are encouraging many people. I still think the hobby- old and new, is massively against hybridizing.

I'm very glad Ed K. is keeping that site and pics up.
