Species Description: Calliophis bivirgatus

Common Name: Calliophis bivirgatus
Scientific Name: Calliophis bivirgatus

Habitat: Calliophis bivirgatus, commonly known as the two-striped coral snake, is primarily found in the tropical forests of Southeast Asia. Its range includes countries such as Malaysia, Thailand, and Indonesia, where it inhabits lush, moist environments like rainforests and woodlands. This snake prefers areas with dense underbrush and is often located near streams and rivers, which provide both habitat and a source of moisture.

Physical Characteristics: The two-striped coral snake is known for its striking appearance. Adults typically grow to lengths of about 1.5 to 2.5 feet (0.5 to 0.76 meters), with some individuals reaching up to 3 feet (0.91 meters). They exhibit a sleek, slender body with a vibrant coloration; their most distinctive features include bold black stripes that run along a bright red or orange background, forming a striking pattern that serves as warning coloration. The head is small and subtly distinct from the neck, which aids in its camouflage among leaf litter.

Behavior: Calliophis bivirgatus is primarily a terrestrial snake, spending a significant amount of time hidden under leaf litter or in low vegetation. These snakes are known for their secretive nature and are predominantly nocturnal, becoming active at night to hunt. They exhibit intriguing behaviors such as burrowing and quickly retreating into crevices when threatened, showcasing their elusiveness. This species is also known for its defensive mechanism, where it may display its bright coloration when disturbed.

Diet: The diet of Calliophis bivirgatus mainly consists of small vertebrates, including lizards, frogs, and small mammals. This snake is an opportunistic feeder, utilizing its venom to subdue prey quickly. Their feeding habits make them important in controlling the populations of these smaller animals. The two-striped coral snake employs a “strike and retreat” tactic, allowing it to remain hidden while hunting.

Reproduction: Calliophis bivirgatus is oviparous, meaning it lays eggs. The breeding season is typically between the warmer months of May and August, following which the female can lay clutches of up to 10 to 15 eggs. The eggs are usually deposited in moist, sheltered locations, where they will incubate and hatch after a period of about 60 to 70 days. The newborn snakes are precocial and equipped to hunt soon after emerging from the eggs.

Conservation Status: The conservation status of Calliophis bivirgatus is currently listed as “Least Concern” according to the IUCN Red List. However, habitat destruction and pollution pose significant threats to its population, making it essential to monitor their status closely for any changes that might indicate a future risk of being classified as vulnerable.

Interesting Facts: One of the most fascinating aspects of the two-striped coral snake is its potent venom, which contains neurotoxins that can cause paralysis in its prey. Moreover, its striking color pattern serves as a warning to potential predators, mimicking the appearance of other venomous snakes, thus providing it an additional layer of protection from threats.

Role in Ecosystem: Calliophis bivirgatus plays a critical role in its ecosystem as both a predator and prey. By preying on small vertebrates, it helps maintain ecological balance, while also serving as a food source for larger predators. Its presence indicates a healthy environment, as it reflects the biodiversity of the habitat in which it resides.
