    Helmeted chameleon

    Honestly, my T. hoehnelii are the last chameleons I bring inside in the winter because of cold temps and the last chameleons I bring inside because of hot temps in the summer. They really need night temperature drops, but they can handle temperature extremes quite well in both directions as long...

    Finding Wild Chams

    You can find them in a lot of areas in Kenya. Was there somewhere in particular you were planning to go? There are also many places in Uganda to find them. In both cases, you can even often find them in and around major cities. Chris

    Tongues of three species of chameleon...

    Yep, quite probably all of the above. There are also inherent issues with equitable access to scientific literature that disproportionately impacts researchers outside North America, Australia and Europe, but in this case most of the background articles (particularly on the tongue) are available...

    Tongues of three species of chameleon...

    They suffered from some of the same issues regarding a lack of appropriate background on what has already been done on the topic (part of why they failed to use appropriate terminology in the tongue paper), but they at least focused on comparing different age groups of the same species, so they...

    Tongues of three species of chameleon...

    Not sure, but I would guess so. The author of that study has published other SEM studies on Chamaeleo chamaeleon skin, for instance, so it is possible some of the same specimens were saved and used for these and other studies. In my lab I save the remaining tissue of specimens I use for studies...

    Tongues of three species of chameleon...

    Yep, except in the Nile delta you also find C. africanus coming north with the Nile to the coast, which is why you can also find them in Cairo. They seem to be restricted to that area, however in the northern part of the country. Chris

    Tongues of three species of chameleon...

    If we are talking about the Sidi-Barani on the northwest Mediterranean coast of Egypt, that would be Chamaeleo chamaeleon. If there is another Sidi-Barani in south Egypt, that would have to be C. africanus. So either way they only would have compared two species and many of the differences they...

    Tongues of three species of chameleon...

    Absolutely, and its nice that you do! It can be difficult to critically analyze studies though if you aren't a specialist, so when I see one that I don't think is a good study, I try to chime in so others can see some of those issues with it. Chris

    Chamaeleo chamaeleon

    Unfortunately, when we graphed the measurements of those 145 specimens, on average these differences held true, but there is a considerable amount of overlap in the sexes in their cranial dimensions at all but the largest of specimens (>130mm SVL), and that overlap exceeds 50% of individuals...

    Tongues of three species of chameleon...

    Ugh, this is one of those studies that should have never made it through peer review. Having studied the chameleon tongue for my dissertation, I was shocked to see this published. There are a ton of issues with the authors using completely incorrect terminology for the tongue and hyoid apparatus...

    Chamaeleo chamaeleon

    Its worth noting that the differences in casque size increase with body size, but there is a large range of moderate to small adult body sizes where these casque dimension differences are much less pronounced and even overlap. I performed field work on Chamaeleo chamaeleon in 2017 in Spain where...

    Chamaeleo chamaeleon

    Distinguishing juveniles from adults is difficult from photographs. The best method for this species would be based on body length (Snout-Vent Length), but this is obviously difficult from photographs. After viewing enough images of this species, you could probably start to gauge juvenile vs...

    Clinging to survival: Critically Endangered Chapman's pygmy chameleon Rhampholeon chapmanorum persists in shrinking forest patches

    There has been initial community workshops run by the NGO Biodiversity Inventory for Conservation (https://binco.eu/), and a draft Action Plan for the species is in development. We are hoping that a larger NGO with more resources may also show interest in becoming involved, as that type of...

    Clinging to survival: Critically Endangered Chapman's pygmy chameleon Rhampholeon chapmanorum persists in shrinking forest patches

    Hi Everyone, In 2014 the IUCN/SSC Chameleon Specialist Group (CSG) ran a crowdfunding campaign through Rockethub.com to perform a rapid assessment of the status of Rhampholeon chapmanorum, the most range restricted chameleon. This crowdfunding was supported in no small part by donations from...

    Phylogeography and support vector machine classification of colour variation in panther chameleons....

    Unfortunately the case with F. pardalis needing to be split into different species is far from clear cut, and there is not agreement on whether there is evidence yet to support doing so. With regard to the referenced paper, there was a lot more hype about the new species suggestion of this paper...

    Brookesia therezieni shipment came in today. Need to make sure they’re all therezieni👍🏻

    Yes, the animals in 1, 2, and 4 are definitely B. therezieni. The animals in 3 and 5 may be as well, but look like B. superciliaris. If you can get higher resolution images of the sides of the base of the tail, that would help. Chris

    Can anyone confirm sex on these 2

    These are Brookesia decaryi. I'd need better photos from the side of the animal with the tail base in focus to sex them, however. Chris

    US Exporters!??

    Given that the accuracy of the process has legal ramifications, I doubt anyone would be willing to risk letting someone do that process for them unless somehow their name would no longer need to be the one on the permits. Chris

    Furcifer Campani ( jeweled chameleons)

    Your best bet would be to talk to Kevin Stanford or Nick Henn about their experiences keeping and breeding this species. They have had more success than anyone with them, but they are a challenging species. Chris

    Touching tounges on branches

    Various chameleon species are known to touch branches with the tip of their tongues (which are actually forked much like monitors and snakes), in what is often referred to as a tongue touch behavior. It hasn't been explicitly proven but it is likely that this behavior is actually an effort to...
