A big thumbs up to all you awesome photographers at Treknature for helping to give little guys like me world exposure! BTW I'm a Jackson's Chameleon Chamaeloeo jacksonii
Habitat: We live in East Africa, namely Kenya and Tanzania. We need cover to hide in and prefer to live in trees. We rarely venture to ground except to lay eggs or mate.

Unique Features: The females do not always possess the three horns of the male but are often larger, the average size being between 23 and 54 cms long. In some subspecies, the females have a large horn on their snout and small horns above their eyes, they can also have three reduced horns. All chameleons have a prehensile tail and clawed feet with short necks. Chameleons have independently focussing eyes (which can move in different directions) giving them 360 degree vision.

Interesting Facts :

* Using their eyes independently, they will sit completely still and watch for a prey item to cross their path. When one is spotted, both eyes will converge and it will sway a bit to better its vision and to confirm the distance to the meal. Prey is captured by projecting the tongue, which has a fleshy tip covered with sticky saliva. Prey is then brought back into the mouth, chewed and swallowed. The tongue, one and a half times the lizard's length, can reach full length in a sixteenth of a second.

* They obtain water by lapping drops off leaves.

* In the morning, they will sun themselves, curving one side towards the light and flattening out their bodies and stretching their necks to increase their surface area. Once warmed, they are able to hunt.

* Aggressive behaviour, if any, is usually only evident between males. Male Jackson's are very territorial when it comes to their "perch" or their female and will fight to defend them. The horns on a male Jackson's chameleon are more than just ornamental. However difficult to imagine, a male will use his horns in a ritualised shoving contest with this rival, although it is rare that any injury results

* Chameleons are known as the masters of camouflage having a highly sophisticated and complex ability to vary their skin pigments or chromatophores in skin cells, thus able to change their color and patterns. This is important being slow-moving creatures so chameleons rely on protective coloration for defense. In cases like this, a chameleon might show bright colors which often times mean bad tasting or poisonous to other animals. If this doesn't work they may shift to their drabbest colors and play dead.

Hi Dave.
Cool "two thumbs in one up" shot ;) I like it.
Nice detail, POV, and the whole animal is in..
I did a quick WS to reduce the flash effect a bit.
Well done.

What a hilarious pose of that chameleon, Dave!
I did not know chameleons had a sense of humour. : )
An interesting-looking creature for sure.
Maybe you could have given him a bit more space
so that your frame would not cover up some of his beautiful body.
TFS. : )

Hi Dave,
This one is excellent! Great pose with a very fitting title. The colors and detail in this are superb. A difficult shot that you manage very well.
