Natural History: 
Bibron’s Coral is a nocturnal species and rarely seen at daytime. Spend most of its life as a burrower and comes occasionally on ground for foraging and mating. Behavior shy, elusive and usually non-offensive. First try to escape under heavy objects but on molestation it flattens whole body and coil up the tail to show alertness or aggression. No specific information is known about its breeding biology. Oviparous, and female probably lays eggs in deep dark places in and around its micro-habitat.
Feeds mainly on other snakes including venomous ones.
Direct threats includes killing on encounter and road kills. Due to loss of rainforests and plantation of its habitat, its population status may get affected because it feeds on other snakes (Shieldtails, Blind Snakes etc) found in its range and they are also sensitive to climate and habitat disturbance.
