>>In the boook "The chameleon handbook" by Francois LeBerre, he mentions that he had previously attempted to interbreed different species of chameleons. It is almost impossible (it has happened before, but not with good results in most cases). Different species have different bodily features like colour patterns, colours, the shapes of their bodies (ie. size of the body or shape of the head), and the horns, casques etc. This makes it almost impossible as the chameleons would barely even think about mating with another species. The only real possible inter-breeding you can do is between subspecies (sometimes), and different colour morphs/areas of origin.
I have to disagree with you. Females of many species look superficially similar. Additionally, males of many species are very overzealous and will try to breed with anything that moves. As a result, this barrier to reproduction relating to the willingness of the animals to breed it not a major factor. While some species are far to different from eachother genetically and morphologically to hybridize, others have not speciated as far away and it is still a possibility. Hybridization of color morphs and localities is a totally different topic although I don't think it should be done either. The bottom line is, cross species/subspecies hybridization isn't always successful, even if copulation is, and it is not recommended by anyone to do it. It happens in the wild from time to time in which case it is refered to as a naturally occuring hybrid (Ch. Ch. calyptratus calcalifer is actually a hybrid of Ch. Ch. arabicus and Ch. Ch. calyptratus). I believe anyone trying to hybridize is foolish and I think most would agree it is detremental to the captive management of these species.
