"Can I breed my panther to my veiled chameleon?"
(Or some such combination.)
In honor of Valentine’s day this year, I thought I would write a little something on chameleon relationships. Or well, perhaps “relationship” is too romantic a word… let’s just say chameleon breeding. I get all sorts of questions emailed to me on an almost daily basis and one I see quite often revolves around a curiosity regarding hybridizing different species. I understand this curiosity, and can even relate to why people would like to do this; to be able to, in a moment of Jurassic World-like manipulation, create a creature that brings together the best components of a few species. Say, the size of a Meller’s chameleon (T. melleri) and the triple horns of a Jackson’s chameleon (T. jacksonii), but with the colors of a panther (F. pardalis.) If such a phenomenal cocktail chameleon existed it’s quite possible that I would be standing in line, money in hand, to purchase one immediately. However, since most of us do not have access to the latest gene splicing lab techniques, this limits us to the basic truths and limitations of breeding and genetics.
“Can these various species mate with each other?”
The answer to this question is that technically, yes, they physically could. Leave a male and female of two different species together and they may do the deed instead of fight with each other. The right question, however, is would such a mating result in fertile and viable eggs? This is where it gets tricky. In order for two species to make viable babies the two species need to be very closely related, and usually that means they are in the same genus (i.e., Furcifer pardalis and Furcifer oustaletii), which usually goes hand-in-hand with how closely the natural territories of the two species overlap. In the case of the two I just mentioned, panthers and Oustalet’s, they would naturally overlap in regions of Madagascar. A panther and a Jackson’s chameleon are too distant, genetically as well as geographically, and not only are they too dissimilar genetically, but they don’t even use the same egg-laying strategy! One lays eggs to incubate while the other incubates internally and gives birth to live young. So such a pairing would never result in anything (except perhaps in injuries!) We face the same problem with a veiled and a panther chameleon, one belongs to the genus Chamaeleo and the other to Furcifer, they are too distantly related because one resides in Yemen and the surrounding areas while one is native to Madagascar. This means the two species probably haven’t shared a common ancestor in some time.
This is not the same type of hybridization people talk about (as a misnomer, in my opinion) when they refer to crossing panther chameleon localities. Panther chameleons, whether they are Nosy Be or Ambilobe or Sambava, are all one single species; Furcifer pardalis. The different color locales came about from a mix of sexual selection and geographical isolation, but they are all the same species nonetheless. So when you cross an Ambilobe with a Nosy Be you are not creating a new species or a hybrid species, like a mule, you still have a panther chameleon but the offspring have lost the uniqueness of each parent’s particular locale.

Your next question may be, “Well, Olimpia, what I’m taking away from this is that certain species could technically hybridize, no?” And you’d be right, very tentatively. There have been reports of chameleon hybrids, but none that I am particularly familiar with nor that I could verify with any certainty. On the Chameleon Forums there was an entire thread about someone who had a clutch of live, viable offspring from a veiled and a Senegal chameleon, if memory serves, but as the months went on the babies perished and they never matured enough to tell if physically they looked differently enough to verify the claim that they were true hybrids. There have also been reports of panther and Oustalet’s chameleon hybrids, but none that I’ve heard about in a long time.
What we can’t say with any certainty at all is whether hybrid chameleons grow up to be healthy, sexually productive individuals or not. I don’t have any information about this, unfortunately. And no one, that I am aware of, has ever raised up a hybrid (or several) and bred them to see if viable eggs could be produced.
My recommendation is to leave the subject well enough alone if you are a new keeper and breeder. I understand the curiosity but I would not recommend that anyone try to do this. It is difficult enough for most people to take care of the chameleon species we already have, I would not encourage anyone to try and come up with their own hybrids now and go through what could be an exercise in futility trying to raise weak or sickly babies. Not to mention that it seems like an unnecessary risk to put two adult animals at risk of fighting and injuring each other. This is one of those questions that might be better left as theory and not as practice!
