Overview
Described in 2021 from forested hills in and around the burgeoning metropolis of Guwahati in Assam, India, the Guwahati Bent-toed Gecko (Cyrtodactylus urbanus) is a remarkable nocturnal reptile. Its discovery right on the outskirts of an urban center underscores the wealth of hidden biodiversity persisting within remnant wild pockets of northeast India.
Biology and Physical Characteristics
Displays a slender body with distinctive kinked, angular toes (bent-toed morphology) terminating in sharp curved claws rather than adhesive pads. The dorsal color pattern consists of rich tan-brown adorned with four to five dark brown, cream-edged blotches or wavy saddles. Its golden irises with vertical slit pupils offer exceptional visual sensitivity in near-total darkness.
Behavior and Ecology
Nocturnal and scansorial, emerging at dusk to forage across tree trunks, decaying logs, and rocky culverts. During daylight, it shelters within narrow stone crevices, deep leaf litter, or dense bamboo clumps. It avoids human residences, depending strictly on natural canopy cover and humid substrate moisture for survival.
Conservation and Human Impact
Currently treated as Data Deficient, but facing rapid, acute threats from urban development, residential construction, road widening, and dumping of waste within urban reserve forest patches around Guwahati. Scientists advocate for community reserve status for remaining hill forests.
Interesting Factoid
Despite being named ‘urbanus’ because it was discovered in the vicinity of a major metropolitan capital, this gecko steadfastly refuses to enter modern concrete houses, preferring damp forest bamboo thickets.
