Trachischium lalremsangai
Why in News?
Trachischium lalremsangai is in the news because a team of Indian and German scientists officially discovered and described it as a brand-new species of burrowing, worm-eating snake native to the forests of Northeast India and Myanmar.
Discovery Details and Habitat
- The Researchers: Discovered by a joint team consisting of Virender K. Bhardwaj, Amit K. Bal, and Chhangte L. Tluanga from Mizoram University, alongside Zeeshan A. Mirza from Germany's Max Planck Institute for Biology.
- Primary Habitat: The live holotype specimen was found inside Murlen National Park, situated in the Champhai district of Mizoram near the India–Myanmar border, at an elevation exceeding 1,500 metres.
- Ecological Hotspot: The species is native to the Indo-Burma biodiversity hotspot, a vast regional ecosystem south of the Brahmaputra River noted for high levels of biological endemism.
Physical Characteristics and Appearance
- Scales and Shine: The snake features exceptionally smooth and iridescent dorsal scales arranged uniformly in 13 structural rows across its body.
- Coloration: Its back (dorsum) is brown, while its belly (ventral side) starts as creamish-white near the throat and transitions into a darker brown with white-speckled detailing toward the tail.
- Size: Classified as a relatively large-sized member of its genus, it reaches a snout-to-vent length (SVL) of roughly 351 mm to 432 mm.
- Head Features: Structurally unique skull features differentiate it from relatives, notably possessing two postocular scales and a distinct arrangement of temporal scales on the sides of its head.
Behaviour and Dietary Habits
- Fossorial Nature: It is a strictly fossorial (underground-dwelling) snake that spends most of its life hidden beneath loose soil and leaf litter.
- Worm-Eating Diet: Belongs to the broader genus Trachischium—commonly referred to as slender or worm-eating snakes—and feeds primarily on earthworms and soft soil invertebrates.
- Harmless to Humans: True to the colubrid group of slender snakes, Trachischium lalremsangai is completely non-venomous and poses zero threat to human safety.
- Genomic Milestones: It is documented as the 11th recognized species under the Trachischium genus globally, filling a critical evolutionary gap regarding how these subterranean reptiles spread across the Eastern Himalayas.
