serpents

Le Sri Lanka abrite une grande diversité de serpents, venimeux et non venimeux, qui prospèrent dans ses forêts et ses zones humides. Si certains représentent un danger, d'autres contribuent à la régulation des populations d'espèces nuisibles. Cependant, la destruction de leur habitat et le commerce illégal menacent leurs populations, ce qui rend indispensables des efforts de conservation.

Drummond-Hay's Shieldtail

Scientific Name: Uropeltis drummondhayi

Family: Uropeltidae

Common Name(s): Drummond-Hay's Shieldtail

Overview:

Drummond-Hay's Shieldtail (Uropeltis drummondhayi) is a species of non-venomous, burrowing snake endemic to Sri Lanka. As a member of the Uropeltidae family, which includes other shieldtail species, this snake is known for its distinctively shaped tail, which is flattened and shield-like. These adaptations allow the snake to excel at burrowing and provide protection against predators. Drummond-Hay's Shieldtail, like its relatives, is primarily fossorial (burrowing), spending most of its life underground in Sri Lanka’s tropical forests.

Physical Description:

Size: Drummond-Hay's Shieldtail is a relatively small snake, typically reaching lengths of 30 cm to 50 cm (about 12 to 20 inches).
Coloration: The snake's body is typically brown, reddish-brown, or purple, with a lighter underside. The exact coloration can vary slightly depending on the region, but it generally blends well with the forest floor.
Tail: The most notable feature of Drummond-Hay's Shieldtail is its tail, which is flattened and shaped like a shield. This tail is used to help the snake burrow and as a defense mechanism against predators.
Head: The head is small and somewhat indistinct from the body, which is characteristic of most burrowing snakes. The head is slightly flattened, making it better adapted for moving through soil.

Habitat and Distribution:

Geographical Range: Drummond-Hay's Shieldtail is found exclusively in Sri Lanka, primarily in the island's central and southern wet-zone rainforests. It is endemic to these regions, and its distribution is limited to the dense forested areas.
Habitat: The species thrives in moist, tropical environments, particularly in areas with rich soil and high humidity. It is typically found in leaf litter, under rocks, or in loose soil where it can burrow and seek shelter.

Behavior and Diet:

Fossorial Lifestyle: As a burrowing snake, Drummond-Hay's Shieldtail spends the majority of its time underground. It is adapted to a fossorial lifestyle, using its specialized tail to help it navigate through the soil. This behavior also keeps it hidden from predators.
Diet: The diet of Drummond-Hay's Shieldtail primarily consists of invertebrates such as earthworms, insects, and other small arthropods. The snake uses its burrowing habits to hunt and forage for food in the soil.

Reproduction:

Reproductive Mode: Drummond-Hay's Shieldtail is ovoviviparous, meaning that the female gives birth to live young rather than laying eggs. The offspring are born fully formed and able to begin their independent lives shortly after birth.
