About Japalura tree dragon
The Japalura Tree Dragon
The Japalura tree dragon, scientifically known as Diploderma splendidum and also called the green striped tree dragon or splendid japalure, is a species of agamid lizard native to the temperate yet humid lowland jungles of the Yangtze River Basin in southwestern China. This species is recognized for its distinctive coloration and is also notable for its presence in the international pet trade.
Physical Characteristics
The Japalura tree dragon possesses a head covered in medium-sized, rugose, juxtaposed scales. A median series of slightly enlarged subconical scales forms a faint ridge on the snout, flanked by considerably enlarged anterior canthal scales. The body is covered with imbricate, strongly keeled scales that vary in size, with some enlarged scales scattered across the back and sides, often tending to form longitudinal series. The nuchal crest is very feeble, composed of slightly enlarged, denticulate scales, and is continuous with an even more feebly developed dorsal crest. Adult males, as described in the type specimen, often exhibit a dark brown head conspicuously marked with yellow spots and streaks, with a yellow band extending from below the eye. The back is typically dark brown with a broad, light stripe on each side, and the belly and tail are dusky.
Habitat and Diet
This lizard inhabits the lowland jungles surrounding the Yangtze River. Its diet is primarily insectivorous, consisting of insects. However, recent research has indicated that due to the presence of specific bacteria in its gut flora, the Japalura tree dragon may also occasionally consume plant matter, suggesting a degree of herbivory.
Health and Pathogens
Studies have identified a total of 26 species of potential human pathogens within wild specimens of Diploderma splendidum, found in both their gut and oral cavities, including bacteria such as Clostridium perfringens, Staphylococcus aureus, and Mycobacterium tuberculosis. The species also harbors specific parasites like the nematode Rhabdias megalocephalum. Consequently, keeping these lizards in captivity is considered to carry a high risk of potential disease transmission to humans through bite wounds or contamination of food and water with feces.

It possesses a feeble nuchal crest continuous with an even more feebly developed dorsal crest. Its back and sides are covered with imbricate, strongly keeled scales, often with scattered enlarged scales.
Are Japalura tree dragons dangerous to humans?
Wild specimens of Diploderma splendidum have been found to carry a significant number of potential human pathogens in their gut and oral cavities. Keeping these lizards in captivity could pose a risk of spreading infectious diseases through bites or contaminated feces.
What are some notable features of the Japalura tree dragon's coloration?
An adult male type specimen was described with a dark brown head marked with yellow spots and streaks. A yellow band runs from behind the nostril beneath the eye. The back is typically dark brown with a conspicuous light stripe on each side, and a dark zone below these stripes.
