Beddome's Cat Snake

Fascinating facts about the Beddome's Cat Snake

• When you trek through the misty Western Ghats, you might spot a slender, gray-brown snake with a head that looks set apart from its neck – that’s Boiga beddomei, a rear-fanged cat snake named for 19th-century botanist Richard Henry Beddome. Its body is wrapped in 19 oblique rows of dorsal scales, with a noticeably enlarged, hexagonal vertebral row that sets it apart from most other colubrids. This distinctive scalation hints at a lineage that has adapted to slipping silently through dense foliage.
• B. beddomei is strictly nocturnal and spends its evenings high in the evergreen trees of the Western Ghats, up to 1,000 m (3,300 ft) above sea level.
• The diet of this snake includes dragon lizards, geckos, skinks, and frogs.
• Counting the belly scales of a captured specimen reveals a range of 238–252 ventrals and 113–127 subcaudal scales. Those precise numbers are more than trivia; they allow herpetologists to differentiate B. beddomei from its close relatives in the Boiga genus, illustrating how detailed morphology is a key tool in taxonomy.
• Unlike many snakes that give birth to live young, B. beddomei lays eggs – it is oviparous.

About the Beddome's Cat Snake

Beddome's cat snake, Boiga beddomei, is a sleek, rear-fanged colubrid that slips through the evergreen forests of India's Western Ghats with an elegance that belies its modest size. Its slender body is capped by a head that clearly separates from the neck, and its dorsal scales, arranged in 19 oblique rows, feature a striking pattern of grayish-brown ground colour crossed by dark brown vertebral bars, while the ventral side glows a yellowish-cream dusted with blackish speckles. The vertebral row swells into a pronounced, hexagonal ridge, a distinctive hallmark among its congeners. By night, this arboreal hunter climbs the canopy up to 1,000 m, its nocturnal habits allowing it to ambush a menu of dragon lizards, geckos, skinks and frogs, all captured with the subtle efficiency of its rear-fanged apparatus. A surprising trait for a forest dweller is its oviparous reproduction, laying eggs that hatch into miniature replicas of the adult, ready to inherit the same twilight trails of the Western Ghats. The snake’s presence in the hill ranges of Maharashtra, Bhimashankar, Mulshi, Koyna, Vasota, Gujarat, Goa and northern Karnataka underscores a distribution as fragmented as the forest patches it calls home, inviting further study of its ecological niche.
