### Identification The Adang-Rawi Rock Gecko (*Cnemaspis adangrawi*) is a master of camouflage, measuring a modest 36–42 mm from snout to vent. Its body is a sophisticated mosaic of grey, tan, and charcoal, perfectly mimicking the lichen-spattered granite it calls home. Look for a distinct, dark "collar" or chevron marking at the base of the neck and a series of irregular dark blotches along the spine. Unlike the vertical "cat-eye" pupils of nocturnal geckos, *C. adangrawi* possesses prominent round pupils, a tell-tale sign of its daytime lifestyle. Its limbs are long and slender, ending in bird-like, non-retractile claws that provide incredible grip on vertical stone.
### Habitat & Range This species is a true "micro-endemic," found nowhere else on Earth except the Adang-Rawi Archipelago in Thailand’s Tarutao National Marine Park. It is strictly rupicolous (rock-dwelling), haunting the massive, shaded granite boulders nestled within lowland evergreen forests. You won't find them in the canopy; they cling to the cool, humid microclimates provided by deep rock fractures and overhanging ledges near sea level.
### Behaviour Observing this gecko requires a keen eye and frozen posture. They are diurnal and crepuscular, most active during the soft light of early morning or late afternoon. Their movement is jittery—a series of lightning-fast scuttles followed by absolute stillness. They are highly territorial; a single large boulder may be ruled by one dominant male who monitors his stony kingdom for intruders or potential mates.
### Diet As an opportunistic insectivore, it employs a "sit-and-wait" hunting strategy. It remains motionless until a small invertebrate—typically a forest ant, tiny beetle, or jumping spider—strays too close. With a sudden, explosive lunge, the gecko snaps up its prey before retreating into a crevice to swallow.
### Fascinating Fact While their topsides are dull to blend with the rocks, males possess vibrant yellow pigment on their underbellies and the underside of their tails. This "secret" coloration allows them to signal their fitness to rivals or mates while remaining completely invisible to predatory birds circling overhead!
