This is the largest member of the Gekko family with an overall adult size of 280mm-340mm. Females are smaller at around 220-270mm. They are powerfully built animals with very agile and muscular legs, a well defined and immensely powerful head and jaw and undivided toes lined with lamellae. The tail is thick set and not obviously prehensile, possibly due to the incredible efficiency of the feet. The tail like the body but to a greater degree is covered with conical protrusions. The conical protrusions are larger either side of the cloacal opening, being larger in males (although this could simply be attributed to the overall larger size of the male.) Colouration of normal –wild type Tokays is highly variable dependant upon time of day captured and location captured. Most normal Tokays in the pet trade have a base colour ranging from dark blue, light blue, grey to almost silver to almost black. Various pale brown, orange through to red dots appear on the body as well as slightly lighter blue small dots inter-dispersed apparently randomly. Like many geckos Tokays go through an ontogenetic change from being neatly banded to randomly dotted (not dissimilar to Leopard Geckos – Eublepharis Macularius). The previously mentioned random light blue dots play a part in the original banding helping to break up the darker base colour of neonates.

Descriptions of current colour morphs experienced:
Powder Blue:
Powder blue is by far one of the most popular of the colour morphs it is also one of the most common. The base colour is a light blue with the tips of the tubercular scales being lighter still. There is no pattern to speak of. Eyes are golden with brown veins. Throat is pigmented. Belly has a slightly more yellow blue appearance than the trunk. When cool/unexcited colours are far darker almost approaching dark grey, tubercular scales still have a lighter hue in this state.

Blue Headed Green:
Blue headed green is another relatively common colour morphs of Tokay. The base colour of the head is the same as for powder blue yet at the collar the colour changes to a pastel green. Tubercular scales on trunk are the same colour as the head. There is no pattern to speak of. Eyes are golden with brown veins. Throat is pigmented. Belly has a more yellow hue and this yellow is stronger than seen in the belly of Powder Blues. When cool/unexcited colours are very dark green and on occasion almost black, tubercular scales still show lighter hues even when in this state.

Blue Granite:
Blue Granite is just a name the author has given this male and it seems to fit. The base colour is a light-ish blue green with lighter blue cross bars including intersected tubercular scales. Speckling on the head is lighter than the body being an almost grey purple. These speckles and dots seem to have a golden outline which is most fetching. On the trunk the colours present in varying degrees are hues of light blue, green/blue and yellows. The largest spots seem to be arranged in loose rows with smaller dots loosely around them. The largest spots centre on tubercular scales but spread out past the base of the scale where it meets the rest of the trunk skin. Legs take on a more greenish/yellow hue and the belly is still blue. Eyes are Grey/blue with darker veins, pupil has a light blue/white outline. The throat is pigmented. When cool/unexcited most traces of blue are lost and the overall colour is grey with black blotches, the tail is also black. Unlike the two previously mentioned morphs instead of the tubercular trunk scales being lighter than the body on Blue Granites they are much darker.

Blue & Green/Yellow Granite:
In the authors personal opinion the Blue & Green/Yellow Granite is one of the most attractive geckoes he has ever seen. This is the name that this morph arrived with although the author has some doubt as to whether it is indeed granite as granites seem to have darker and on occasion black spots which this morph is totally devoid of. Base colour is either green or yellow dependant upon mood and time of day. Feet are always yellow with blue dots. On the trunk blue saddles are prominent which are edged by turquoise dots. The head pattern is paler with a more blue overall hue. The belly is green/yellow with sporadic blue speckling. Eyes are gold with brown veins. The throat lacks pigment. When cool/unexcited the overall colour is much darker with no sign of the beauty beneath.

Blue & Orange Granite:
This female was bought as a granite but is totally different to the blue granite male. The head base colour is blue with orange dots lines with a deep lichen green. The body base colour however is grey through to lichen green dependant upon mood/temperature. Tubercular scales on the body are either coloured a rusty orange or light blue, making the pattern of this granite female particularly busy. The belly is blue with sporadic orange speckles. Eyes are gold with brown veins. The throat is pigmented. When cool/unexcited this lizard is very drab with none of the mixtures of colour mentioned above.

Blue Granite Calico:Either termed blue calico or blue granite calico either way this female is very interesting. This female was bought as a standard calico but from the picture it becomes rather obvious she is not. Head markings are standard for calicos in that she has an apricot head, but that is where the similarity ends. The body is a deep blue with lighter watercolour wash of light blue. Sporadic very small orange spots are present. Belly is blue with small orange freckles. Eyes are black with some silvery/white detail, pupil is black. Throat lacks pigment. Cool/unexcited colours are very drab, the full body goes very dark grey almost approaching black. The unexcited colours were retained up until a few weeks ago after a period of some three months settling in period.

Calico:
It is quite clear that I have two different types of Calico, what may well be the case is the resounding differences surrounding the two normal Calicos. The one pictured is the female. Each calico obviously has differing amounts of pigmentation as pigmentation is lost through time and there is discussion suggesting that most calicos will become leucistics if given enough time. The author has seen young adult leucistics though and that seems strange if the process is solely a time thing or again whether there are two differing types. There seems little point in discussing patternation due to variablility apart from the fact that calicos usually have an apricot head, black eyes with silver veining and varying black grey patches.

Hypomelanistic:
Hypomelanistic Tokay Geckos usually arrive graded A,B,C. A being the best coloured. The female pictured is an A grade Hypo, where as the male came in as a C grade. The difference is marked and whilst it is apparent the male is not normal, I’m not sure he is a hypo either. Description on such a sliding scale is difficult. The female in my possession has a lilac head with vivid orange spots, the body however has a pastel lavender base colour and the orange dots loose the intensity seen on the head. Occasional lighter blue flecks appear and seem to congregate down the centre of the dorsal area. The eyes are gold with light brown veining. The throat in the female lacks pigments whilst the male has pigment.

Patternless Axanthic:
This is the authors opinion is one of the most interesting morphs here whilst not necessarily being the most eyes catching. The Patternless Axanthic was sold to the author as a C grade Axanthic but it has become quite apparent she is any thing but! The body has grey/brown flecks which look to be receding leaving an apricot/white colour. The body looks to have blushing from the belly half way up the flanks. The dorsal colour is a very faded light brown wash, the lower flanks and belly colour is porcelain white. The legs and feet are also white. The eyes are black and the throat lacks pigment. This could well be either a Patternless calico or an Axanthic calico, but time will tell to see if the white spreads further.
