Actually, H. gigas do not ALWAYS posture defensively prior to biting, so one must still use caution when handling them, even when they are not acting in a defensive manner and it doesn’t take much “pestering” to rile some specimens. For that matter, I have worked with a few Naja that would not hesitate to strike without acting outwardly defensive. In short, one cannot base the character of a given snake by its genus, spp. or ssp., as each are individuals harboring individualistic characteristics. Heck, I recall Gary Johnson, herp curator at the Louisville Zoo, telling me about a male D. couperi at Zoo Atlanta which was maintained within a “walk in” type naturalistic enclosure, complete with a colony of Gopherus ployphemus and burrows. Apparently, this particular male was quite territorial and would literally race out of any given burrow and defend its territory against any would be trespasser, generally the keepers. Apparently, it got to the point where no one wanted to maintain the exhibit! Now, eastern indigos are normally gentle giants and having worked with them for the better half of 30 years, in both captivity and the wild, I can attest that I have never seen one behave in such a manner in either environment. Personally, I would have second thoughts regarding the entrance of such a large exhibit, knowing there was 8’ of the reptilian version of the pit-bull somewhere in one of many holes just waiting for me! So, once again, animals do not always behave in the manner they are “supposed” to, simply because they are a member of this genus or that. ;0)
As for price, I have noticed a slight increase in the price of H. gigas over the past couple of years or so, but as you have indicated, they shadow in comparison to most available Drymarchon spp., with perhaps the exception of D. m melanurus, which I have found to be quite comparable in the way of price. Of course, supply and demand is always an issue and Drymarchon spp. are generally in greater demand and given H. gigas are venomous, as you have already indicated, often places a damper on the desirability of the species, especially in light of the somewhat recent studies indicating the toxicity and nature of the venom they harbor. When you toss in the number of states and municipalities that harbor regulations surrounding the keeping of venomous reptiles, even opisthoglyphic specimens, the number of folks within the hobby able and willing to keep such specimens simply begins to plummet. It’s unfortunate, as H. gigas generally make fascinating and relatively easy captives…
