### Identification The Nine-Keeled Grass Lizard (*Toenayar novemcarinata*) is a master of mimicry in the vertical world of the undergrowth. This slender, elegant lizard is instantly recognizable by its namesake feature: nine prominent, longitudinal keels (raised ridges) running down its dorsal scales, giving its back a rough, corduroy-like texture. Typically reaching 25cm in total length—though the whip-like tail accounts for nearly three-quarters of that—it sports a burnished bronze-to-olive dorsum. A striking, cream-colored lateral stripe runs from the snout to the hind limbs, bordered below by a deep chocolate brown. To distinguish it from the similar *Takydromus* species, look for the "double-spot" of iridescent turquoise just behind the forelimbs, which flares brilliantly in males during the spring.
### Habitat & Range This species is a specialist of the humid, montane grasslands of the Indo-Burman highlands, typically found at elevations between 800 and 1,600 meters. They favor "edge habitats" where primary broadleaf forests give way to dense stands of elephant grass and ferns. They are rarely seen on the forest floor, preferring the sun-drenched mid-canopy of tall grasses where the light is dappled and golden.
### Behaviour Observing a *Toenayar* is a lesson in patience. They are "grass-swimmers," using their exceptionally long, semi-prehensile tails to distribute their weight across swaying stalks, allowing them to move through the canopy without touching the ground. Strictly diurnal, they emerge at dawn to bask on flat leaves. If you startle one, it won't retreat into a burrow; instead, it performs a "stiff-legged" leap into the dense thatch, vanishing into the shadows with a rustle that mimics the wind.
### Diet A voracious insectivore, it specializes in stalking small orthopterans. It employs a "slow-creep" hunting style, inching toward its prey before delivering a lightning-fast terminal strike. It is particularly fond of small grasshoppers, leafhoppers, and orb-weaver spiders.
### Fascinating Fact The nine keels on its back aren't just for protection—they are sophisticated water-management tools. During heavy monsoon rains, the micro-grooves between these keels channel water away from the lizard’s nostrils and eyes toward its flanks, allowing it to remain perfectly still and breathe effortlessly even during a torrential downpour!
