Since 1993


Toothless Reptiles is an independent monitor breeding facility and we are just that, independent. I have no agendas and I do not do this as my main source of income. I want to provide you with a fun and involved experience because that is what I expect for myself. If this was not fun I would not be doing it, that is why I go the extra mile to talk to non-customers and to send out T-Shirts, temperature probes, and even the egg that your monitor hatched from with every sale. I am able to keep my prices very competitive because my overhead is quite low given the fact that my normal job pays all my bills. This is also the reason why I generally go long periods of time between clutches as I do not need to stress my monitors out with constant production. In my case, what is best for my animals is always what is best for me too. I am simply a reptile enthusiast just like each and every one of you who happens to have the resources to be able to produce some awesome monitors. After breeding monitors for over 12 years now I am simply wanting to share them with you. Keep Feedin’ -Cory

worlds first scientifically verified parthenogenic water monitor

Toothless Reptiles has been funding a few different DNA projects (check out the services tab for info) and one of the reasons for that is the fact that we produced a parthenogenic animal. After more than a year of development we have finally been able to prove out our suspicions with preliminary testing!


“These data represent the results from four water monitors, M1 –adult female, M2 – her alleged parthenogenetic offspring, M3 –her sexually reproduced offspring and M4 -an “unrelated” adult female.   We would expect only a modest amount of genetic variation in this small sample due to various historical aspects of the captive and wild populations.  (Note: the female herself is homozygous at all four loci.) However, what little genetic variation that is exhibited (red allele sizes) fits the pattern of what we might expect from these four individuals.”



     Basically, row M1 expresses the same values over all 8 alleles as M2 because M2 is the parthenogenic offspring of M1. With parthenogenesis we know that all the genetic material, regardless of sex, comes from the female alone. M3 expressed a variation in allele 2 of primer set 7 and retained its similarities to M1 and M2 across all others because this animal is a normally fertilized offspring of M1. This variation, in theory, was introduced by the animals biological fathers’ DNA. M4 is completely unrelated to all other animals tested but is expressing some similarities that we think is due to the lack of genetic variation in the species. Obviously, we will be doing further testing utilizing all 12 of our primer sets for 24 alleles with more genetically diverse samples to give us a better spectrum but great data so far. Using the data, we have right now, Toothless Reptiles has produced the world's first scientifically verified parthenogenic Varanus Salvator. Pretty cool. Keep Feedin' -Cory

hybrid project update as of 19 september 2018

There has been some confusion with the project which I can understand is mostly my fault. The initial “First Look” video was taken a few days ago and all the animals, 3 in total, are out of their eggs now. I'm sure you guys understand that given the sensitive nature of the project I wanted to make sure the animals were ok before posting anything which is why I waited a few days to post up the initial video. The next update will include a summary of the project and data in full as well as all the DNA data to verify results. This is, of course, regardless of what those results may be. It is important to note that we are simply looking for a verifiable result here which we have all the material and technology to do. If this project was done by another breeder, their project would be over at this point as they do not possess the necessary resources to prove out their animals. The whole idea behind our multiple DNA projects is to alleviate the reptile trade of anecdotal evidence and our projects will be no different. Right now, we are offering a private project with a level of scientific accountability and transparency that is unprecedented. As always, we would love to extend this testing to anyone that wishes to use it. Over the next 6 to 9 months we will keep documenting the development of the animals and when they are of a size that is conducive to pulling an ample amount of blood, we will continue with the DNA testing. We already have samples from the mother and father on file as well as having the world’s first scientifically verified parthenogenic salvator from this same mother (info is on our website homepage). This affords us the opportunity to compare apples to apples and apples to oranges. We are literally dealing with a best-case scenario as the only two options here are hybrid or parthenogenic. There has been some talk about sperm retention which I would encourage people to try to find a single scientific example of sperm retention in large varanus. It just flat out does not exist, and science has continued to prove that theory to be false for over 20 years now. Sperm retention seemed like a much more likely concept when compared to parthenogenesis many years ago. Afterall, parthenogenesis was considered science fiction and was even portrayed as such in the awesome movie Jurassic Park. Every study that was used to attempt to prove sperm retention has always proven parthenogenesis. I’m not exactly sure why people still believe in this or talk about it, but science is not a belief-based system and the information is available to the public. Let’s say for arguments sake that sperm retention does exist; retained sperm from a prior breeding would simply produce a normal looking animal as it is essentially a normal pairing. As far as snout deformation and parthenogenesis, the Argus parthenogenesis project did produce some animals with snout deformations, but these were life ending defects such as partially formed jaws or skulls. This study was also only used to produce a stress driven parthenogenic response not accidental like we see more often in captivity with a much higher success rate. A defect is not generally symmetrical and exaggerated on 100 percent of a clutch with similar expressions. Many modern biologists agree that most of the Varanids must have originated from a single source which served as grounds for the project. You are all welcome to read about it on our website, it’s a short read of about a page and a half. As with all other varanid hybrid projects, the animal’s features tend to favor the mother. This is, in theory, because of the ZZ and WZ chromosome sets and because an overwhelming portion of the physical material used for development comes from the mother. With all that said, I can understand why folks are a little overwhelmed with the project, but I assure you we will continue, and I will be looking forward to posting the results and project up in its entirety toward the middle of 2019. Thank you all so much for your positivity and support. As always, I would be happy to take anyone’s call about any of our projects. Keep Feedin’ -Cory 619-549-1508 Not For Sale
