                    My Collection

                    Geckos From Around the World


                    Geckos in my collection hail from areas throughout the world. I work with gecko species from Australia, New Caledonia, Africa, China, the Middle East, and South America. The diversity of geckos throughout the world is truly astounding and with so many species that I find cool and interesting, I have no doubt that I will continue to add new species each year. Check back often for updates.


                    Geckonia (Tarentola) chazalia
                    Helmeted Gecko

                    The helmeted gecko is the favorite terrestrial species that I currently keep. The distinctive row of enlarged scales at the base of the skull give this gecko its unique look and common name. Alert, active, and fearless, these small geckos pace back and forth along the front of their tanks hoping for a handout when I enter the room.  Many nocturnal terrestrial species are shy and rarely seen- this is not the case with these active little geckos. They will aggressively take food items from tongs or my fingers. Once relatively common in the hobby, this species has become increasingly difficult to find. I have had good success breeding this species, hatching out 20+ babies in 2009 / 2010. I currently have several young female holdbacks that should start producing in 2011.


                    Rhacodactylus ciliatus
                    "Crested Gecko"

                    Easy to care for, widely available, and coming in many colors and patterns, crested geckos are often considered the ideal starter gecko. However, the genetic possibilities of this species appeal to even the most advanced keepers.  I work with a couple of breeding groups of crested geckos and have refined certain traits over several generations of selective breeding, and this is one of the species I am probably best known for.  I almost always have crested geckos available for sale. If I had to limit my gecko collection to a single species, the crested gecko would have to be my choice. I had 4 females producing in 2010 and am excited by the progress my selective breeding projects are showing.


                    Rhacodactylus chahoua
                    Mossy Prehensile-tailed Gecko

                    This slightly larger cousin of the crested gecko has a unique personality and a cryptic coloration of mossy greens, browns, and grays that afford this gecko wonderful camouflage amongst the bark and vegetation of its habitat. I have a pair of nice Pine Island chahouas that were successfully bred for the first time in 2011. As much as I like this species, I will undoubtedly be adding more to my collection in the future.


                    Rhacodactylus sarasinorum
                    Sarasin's Giant Gecko

                    Picture
                    Another close cousin of the ever popular crested gecko, Rhacodactylus sarasinorum at first glance may appear very similar to a ciliatus without the crests. To me the sarasinorum have more of a "long and lean" look to them. Some selective breeding for specific traits has begun on a very limited basis, but most of these geckos still exhibit a "wild look". They tend to be a bit quicker than crested geckos, and perhaps a bit more nervous, but some report that they tame down quite easily with consistent handling. My pair comes from Allen Repashy. They bred for the first time in 2011.

                    Eurydactylodes agricolae 
                    Chameleon Gecko

                    Another native of the island of New Caledonia, E. agricolae can be kept in much the same manner as crested geckos, but in smaller enclosures as they are a much smaller gecko than any of the Rhacodactylus. At first glance, these may appear to be a rather small, drab gecko, but it is upon closer inspection and observation that the unique nature of this gecko can be appreciated. This is a relatively slow moving gecko which likes to hug tightly to a vine, branch, or even your finger. Their coloration allows them to blend into their environment perfectly. I have hatched out a good number of these over the last few breeding seasons, and have 2 unrelated pairs producing.


                    Nephrurus milli
                    Australian Thick-tailed Gecko

                    While not as commonly available as such species as crested geckos or leopard geckos, N. milli are considered to be one of the best starter geckos for those who wish to work with members of the Australian "knobtail family".  Not quite as shy as some of the other Nephrurus geckos, the milli are an attractive and entertaining subject to observe, and will even tolerate a small amount of handling. You've just got to love those big, dark Nephrurus eyes. I currently keep several pairs of milli and produce young on a consistent basis.


                    Nephrurus levis
                    Smooth Knobtail Gecko

                    Picture
                    The newest addition to my group of Australian geckos are a young pair of Nephrurus levis geckos. These are sometimes referred to as "smooth skinned" knobtails as opposed to the "rough skinned" knobtails such as Nephrurus wheeleri or Nephrurus amyae. These geckos are kept a bit moister than their rough skinned cousins, and often burrow into moist sand or kick sand to close the opening of their hide to help preserve moisture. Like all the Nephrurus geckos, the big dark eyes and perpetually "smiling" appearance make these a very visually appealing gecko. They have been on my "wanted list" for quite a while and I look forward to getting eggs in 2012.

                    Nephrurus wheeleri
                    Rough Knob Tail Gecko

                    Only a few short years ago, Nephrurus wheeleri were very hard to come by and demanded top dollar. Today, availability has increased and the price has dropped to a level that shouldn't be too daunting to the serious hobbyist. This prehistoric looking gecko from the arid deserts of Australia is relatively easy to keep and can be quite prolific. The roughly scaled skin sets this group apart from the smooth skinned knobtails. Hatchling wheeleri are robust and very easy to work with.


                    Goniurosaurus hainanensis
                    Chinese Cave Gecko

                    The Goniurosaurus genus contains some truly stunning species. The deep red eyes are a distinctive feature. The hainanensis are relatively easy to keep and breed as long as proper care conditions are met, but don't let the sometimes used common name "Chinese leopard gecko" fool you into thinking these can be kept the same way as the "leopard gecko" which is found in almost every pet store.  Goniurosaurus are a very shy and reclusive group of geckos, and can be stressed by excessive handling and human activity. I see mine less than any of my other species, but when I do, I still marvel at the beauty of this species. I am not currently breeding this species.


                    Goniurosaurus luii
                    Chinese Cave Gecko

                    Picture
                    A couple of years ago, I saw some young G. luii available at a reptile show and they really grabbed my attention. The orange coloration was almost electric! After a quick look around the show to see what else might be available, I decided to buy them, but found that they had quickly sold out. Since that time I have been on the lookout for some and finally picked up a juvie pair at Tinley. This is a strikingly colored member of the Goniurosaurus genus, and somewhat hard to find compared to the more common G. hainanensis. Like all Goniurosaurus, they are a shy species, but I find my luii to be more visible and not quite as shy as my hainanensis. I bred this species for the first time in 2011.

                    Palmatogecko rangei
                    Web-footed Gecko

                    Web-footed geckos are uniquely adapted to the sandy environment of the Namibian desert of Southern Africa. The webbed feet of this species are unique in the gecko world and allow this gecko to easily traverse the soft sands of its native habitat. This small gecko may appear somewhat fragile, but is surprisingly tough. In their native habitat, they have been observed active at temperatures barely above freezing! They have recently been reclassified as members of the Pachydactylus genus, but the old moniker of Palmatogecko still seems to be more widely used. In addition to the unique toes, the eyes of this species are spectacular. Finally, after some setback with this project, I should produce some offspring in 2012.


                    Eublepharis macularius
                    Leopard Gecko

                    The leopard gecko is the most widely available and  captive bred gecko in the world. The number of different genetic morphs that have been created within this species is truly incredible, and hard to keep up with, as they change so rapidly. I kept leopard geckos back in the late 1990's and am amazed at how much change has occurred in the last 10 years. I have a single pair of leopard geckos which I keep in my high school science classroom at the school where I teach. The students enjoy observing the animals each day.  Along with crested geckos, leopard geckos are usually recommended as the ideal "starter gecko" for those buying their first animal.  One of these days, I may put this pair together, but it's not a high priority.


                    Chondrodactylus angulifer
                    Namibian Giant Ground Gecko

                    Picture
                    Male
                    A new addition in 2010. I have been looking for this species for a couple of years. This is another gecko adapted to the harsh desert environment of Namibia. They have powerful jaws which are said to be capable of delivering a painful bite. There's something about big "blockheaded" geckos that I like. This species is also interesting in that the males are easily distinguished from the females by a row of white spots which the females lack. I currently have 2 breeding groups and produced offspring for the first time in 2011.

                    Pristurus carteri
                    Scorpion Gecko

                    Picture
                    Female
                    Another new addition in 2010, these unique geckos have been on my watchlist for a while now. These small, diurnal geckos are alert and watch my every move when I enter the gecko room. The common name "scorpion gecko" comes from the interesting way these geckos arch their tails over there backs. It is said that the tails play a role in communication. This pair will be put together for breeding in 2012. I would be very pleased if I succeeded in breeding this uncommon species.

                    Gonatodes vittatus
                    Wiegmann's Striped Gecko

                    Picture
                    Officially the smallest gecko in my current collection, I picked up a couple of young, unsexed Gonatodes vittatus in the spring of 2010. The males of this genus often exhibit strikingly beautiful colors and patterns, while the females are much less flashy. I believe the two I picked up are both males, as both are now starting to exhibit the bright white dorsal line and bits of bright yellow around the head and throat that are commonly seen in males of this species. I may be looking for a female or two in the future if I choose to start a breeding group of these brightly colored little "mini-geckos".

                    Oedura castelnaui
                    Northern Velvet Gecko

                    Picture
                    I have a single, unsexed, amelanistic Oedura castelnaui which I picked up in the spring of 2010. While this gecko was picked up as an afterthought addition in a package deal, I have often considered adding an Oedura to my collection. This was a chance to "get my feet wet" with this genus so-to-speak without investing too much in a project. While many have focused on producing amelanistic castelnaui, I find the "normal" color phase quite attractive as well.

                    Diplodactylus galeatus
                    Australian helmeted gecko

                    Picture
                    This species has been on my wanted list for a few years. I've always thought they were one of the nicest looking of the Diplodactylus group. I have a 1.2 group that should start producing in 2012

                    Pachydactylus caraculicus

                    Picture
                    I'm dipping my toes into the Pachydactylus pool a bit here. This is a very diverse group with some really unique individuals. Often the babies are born with amazing colors and patterns that break up into a more diffuse pattern as the geckos mature. The yellow and orange bands on the tails of these young ones are just electric! It will be interesting to see how they change over time.

                    Haemodracon trachyrhinus
                    Pigmy Socotran Leaf-toed Gecko

                    Picture
                    Photo by Roberto Sindaco. Used with permission.
                    This gecko's genus name Haemodracon means "dragons blood" - named for the Dragon's Blood Trees found in their unique environment. The species name of trachyrhinus refers to the rough scaled snout of this gecko. The island of Socotra in the Indian Ocean has many very unique forms of life found nowhere else in the world. Unfortunately it lies in the pirate infested waters between Somalia and Yemen, making it highly unlikely that any other animals will come out of that area. I am lucky to be working with these small, unique geckos that are just now becoming available outside of their remote native habitat.

                    Coleonyx elegans
                    Yucatan Banded Gecko

                    Picture
                    I picked up a single Coleonyx elegans at Tinley this year. Of the various species and forms of Coleonyx, I've always liked the looks of this species the best. So far, I like the gecko and am thinking I'd like to put together at least a breeding pair for the future. I'll raise this one up and see what I have (male or female) and go from there.

                    Rhoptropus biporosus
                    Namib Day Gecko

                    Picture
                    I picked up a subadult pair of Rhoptropus geckos at Tinley this year. I could hardly travel all that way and not come home with something interesting now could I? I always have my eyes open for uncommon and unique species, and this gecko fits both bills. Namibia has already supplied a couple of my favorite gecko species, so one more from this region couldn't hurt. They are a diurnal (day active) gecko like my Pristurus geckos which I very much enjoy. At first these geckos disappeared in a flash if I came close to their tank, but as they have gotten used to me, they have become much bolder and often stay out in the open, following my movements. I think they've figured out that the guy who brings food isn't so scary. I'll have to see if I can get some pictures. Taking pics of small, fast (and expensive) geckos which can climb the sides of their tanks makes me a bit nervous.
