The king cobra (Ophiophagus hannah) isn’t a tough snake to identify. A totally grown grownup simply reaches over 13 ft lengthy, making them the most important venomous snakes on the planet. However regardless of their dimension and iconic look, not less than one susceptible species in India is sneaking aboard trains and by accident arriving into new and harmful habitats.
In a research just lately printed within the journal Biotropica, researchers from Museum Liebnitz in Bonn, Germany, analyzed obtainable verified native cobra stories and rescue information made between 2002 and 2024 within the Goa area of southwestern India. In all, they recognized 47 encounters with the Western Ghats king cobra (Ophiophagus kaalinga) over 22 years. Past the hazard of such conferences, there was a bigger downside: the Western Ghats isn’t endemic to Goa.
Herpetologist and firsthand volunteer king cobra rescuer Dikansh Parmar can personally attest to the problem. His 2017 encounter is one in all his personal research’s 5 separate snake sightings situated on or close to trains. Following extra interviews with native residents revealed the serpents have been additionally noticed in villages and neighboring forests, however nowhere within the surrounding farmland.
“With the elevated international availability of low-cost smartphones and social media lately, the variety of stories of snakes on and round trains in India has elevated, with three incidents recorded in a 30-day interval, and lots of extra rising on social media,” Parmar and his co-authors wrote.
Primarily based on these and different stories, the staff developed a concept: Western Ghats cobras are hitching rides on trains to new locales. They think that the snakes are possible interested in railway vehicles for a mix of causes, together with prey like rodents and the lure of secure, safe shelters.
Their closing locations round Goa aren’t superb, nevertheless. After conducting a species distribution mannequin that built-in components like human exercise, vegetation, and local weather, Parmar then in contrast hypothetically appropriate habitats to the precise cobra rescue areas. His staff found the snakes have one of the best probabilities for survival in Goa’s inside, away from the coast however near rivers and streams in forests. Extra typically, nevertheless, stories positioned the snakes close to railway websites which are drier, extra uncovered, and home fewer prey choices. As a substitute of local weather shifts forcing their migration, Parmar defined one other issue is now at play.
“Our findings counsel a unique, extra passive mechanism: railways could act not simply as corridors for lively motion, however as high-speed conduits,” he wrote “This contrasts with the usually detrimental influence of roads, which frequently perform as boundaries or vital mortality sinks for snakes.”
Parmar’s staff argued it’s very believable that prepare migration routes are a vastly underreported methodology of journey—not just for king cobras, however different susceptible species, as properly. Solely by higher finding out and understanding these conditions can conservationists defend the animals, in addition to any stunned commuters.
