whats everyones opinion of the scalless cornsnakes?
these gonna be as popul;ar as many of the other morphs or gonna be hit or miss, im curious what everyone thinks, thanks

I think visually, they're wicked looking. However, I think it's a fine line in regards to ethics. Their has been a handful of studies done on various scaleless reptile species that state they are susceptible to dehydration and have sun sensitivity. I've even read some studies that suggest the animals are in constant pain. I think more scientific studies should be done before they're mass produced for the public. If in fact they do have health issues, ethically I think the breeders need to look at the quality of life of the animal before their wallet.

Now if these studies were to find that these animals were healthy and happy, I'd love to own one. More needs to be known about them first before any more selective breeding is done in my opinion. |
According to scientific literature, water loss is the same between scaleless snakes and scaled snakes. Granted, this is one of only two papers I could find, and they were both published in the 70s.
Bennett, A.F. and P. Licht. 1975. Evaporative water loss in scaleless snakes. Comparative Biochemistry and Physiology Part A: Physiology 52:213-215. Abstract: 1. Rates of water loss were measured in two aberrant scaleless water snakes, Natrix sipedon, and in six normal animals. 2. Pulmocutaneous water loss of the scaleless animals was equal to or less than that of the controls at 20, 27, and 34°C. 3. The thermal dependence of pulmocutaneous water loss in all snakes was low (Q10 = 1·31–1·89). 4. The proportion of total water loss due to cutaneous evaporation (86·5%) in a scaleless animal at 20°C was similar to that previously reported for normal Natrix. 5. Thus, reptilian scales and their associated features (e.g. thick keratin layers, superficial dermal layer) cannot be considered adaptations for the curtailment of integumentary water loss. These guys worked with Nerodia, which is a water-loving snake (notice the genus change). To be fair though, I don't think behavior (ie. soaking for an aquatic snake) allowed the scaleless snakes to compensate for evaporative loss, because of the following article: Baeyens, D.A. and R.L. Rountree. 1983. A comparative study of evaporative water loss and epidermal permeability in an arboreal snake, Opheodrys aestivus, and a semi-aquatic snake, Nerodia rhombifera. Comparative Biochemistry and Physiology Part A: Physiology 76:301-304. Abstract: 1. Evaporative water loss was compared in two snake species, the arboreal Opheodrys aestivus and the semi-aquatic Nerodia rhombifera. 2. Rates of water loss were significantly higher (P < 0.01) in N. rhombifera than in O. aestivus. 3. Shed epidermis of N. rhombifera was significantly (P < 0.001) more permeable than that of O. aestivus. 4. Following lipid extraction the permeability of shed epidermis increased in both species with the greater increase occurring in O. aestivus. 5. The efficacy of epidermal lipids in reducing cutaneous water loss may be an important adaptation to an arboreal environment in O. aestivus. In short, if there was any difference between the water loss in scaleless and scaled snakes, we should see it in Nerodia, since their skin is more permeable than other species of snakes. Since corn snakes aren't aquatic, their skin probably has a higher fat content than water snakes, and therefore their ability to retain water should be fine even in relatively dry situations. Granted, I have never owned a scaleless corn, so I'm not sure what kind of anecdotal evidence some of you may have. But the scientific literature seems pretty clear... water loss is similar between scaled and scaleless snakes. However, scales have a multitude of functions, not the least of which is protection from abrasions and depredation. In the wild this is probably a very significant danger to scaleless snakes, but in captivity these risks are obviously minimized or non-existent. |

You are right though, the dangers to being scaleless in captivity are much, much less then in the wild. |

now can we please stay on topic? my ? was "these gonna be as popul;ar as many of the other morphs or gonna be hit or miss," do you have anything you can ad to my ? |
my opinion.. don't like them. they're interesting to look at and I wonder if they are soft like petting a sphynx cat, but I want scales on my snakes and I don't really want them to be soft. Color/pattern morphs are fine. again, just my opinion, no offense meant to anyone that likes them
:) will it be popular.. time will tell I guess |
Jason, I think Stephanie was trying to have a discussion on good faith. Your initial question was fairly easy to misinterpret. No reason to get ornery.
Honestly, I like scaleless reptiles. I think the "constant pain" is pretty far fetched and unsubstantiated, since these animals do thrive if taken care of properly. I can see dehydration and perhaps sunburn (?) being an issue for certain species (such as bearded dragon silkies), but other than that, I don't think it's much different than having a hairless rat, cat, or naked bird. |
