Chinese Cave Gecko x Leopard Gecko

[N-E Cichlids]

Never thought My question would go this far. I didn't mean to start a huge in depth debate, but I like to hear everyones opinion.

 

[coura]

Isn't a definition of a species "a group of similar organisms which can reproduce together to produce fertile offspring"? And cross-breeding separate species produces infertile offspring?

It might be a slight confusion on my part, but surely that means breeding these species together will produce infertile baby geckos, which are not a new species, and will be of no use to breed for captivity?

In adicion on what has been said here you got more "artificial" and natural species made from hibridizacion completly fertile: flower horn chiclids(dont know if you know them), domestic angel fish, discus, many livebears, Mauremys iversoni, Cuora serrata, some Cyclura igs, green ig vrs antilean green igs, Rana sculenta, Cuora trifasciata (aparently derived from natural hibridizacion beetwen Cuora pani and Cuora galbinifrons many million years ago),etc.
