can frog cross breed?

Do you have a question about anatomy, life cycle, taxonomy, or anything else that isn't covered by the other frogs.org.au projects? Ask them here (or provide an answer to other people's questions).

It is theoretically possible, however the offspring will be infertile.
It is more likely to occur in species that do not naturally occur in the same area, otherwise there would be lots of infertile hybrids in the wild, which in terms of increasing an individuals fitness (evolutionary fitness not more stamina) is counterproductive. They will have developed means for preventing hybridisation such as different mating 'techniques' timing or conditions required for mating. Whereas species that don't naturally meet in the wild have no need to develop these things so if artificially put together may be able to mate.

An example is the Red and the Grey kangaroo, one occurs in the south and the other in the north so would never naturally meet. But in captivity they are able to cross bread.

It isnt really a good think joe green. In america they have lots of pythons that have cross breeded and now their biodiversity in some areas 'is screwed'

Although in captivity it would be pretty cool.

Also, is there a difference in the 'northern race' of marhies and the southern race' (l. tasmaniensis)

Your right about it being bad in the environment marshie but i was thinking in captivity it would be way cool. Not sure about the marsh frogs though, think they would be the same maybe.

when you say 'northern race' of marshies do you mean l. peroni? If so they are different species one is the 'striped marsh frog' the other is the 'spotted marsh frog.'

The trouble with being "cool" in captivity and bad in the environment is that cool captives can and do escape into the environment, leading to all sorts of biodiversity issues.. If you want fancy-looking frogs, play with Photoshop, not genetics.

I'm more curious about whether frogs cross-dress.
