Annam Kukri Snake – Oligodon annamensis – Leviton, 1953

Science name: Oligodon annamensis – Leviton, 1953

Taxonomic:  Animalia>> Chordata>> Reptilia>> Squamata >> Colubridae >> annamensis

Species status: Endemic ; IUCN status: LC (Least Concern)

Description:

Physical Characteristics:

Information on the physical characteristics of Oligodon annamensis is limited. Members of the Oligodon genus are typically small to medium-sized snakes with relatively short bodies and tails. These snakes are known for their distinct, sharp-edged posterior maxillary teeth, which they use to cut open eggs (hence the name “kukri snake”).
Coloration and Appearance:

Specific details about the coloration and appearance of Oligodon annamensis have not been well recorded. Kukri snakes typically have a pattern of bands or blotches, with colors ranging from brown to reddish or orange hues.

Distribution and habitat:

Elevation: There is no specific elevation range recorded for this species.
Area: Oligodon annamensis is apparently endemic to Vietnam. It is known only from two historic specimens collected in Bao Loc and B’Lao, Lam Dong Province, and a more recent sighting from Tà Đùng National Park in Vietnam.
Habitat: The specific habitat preferences of this species are not well-documented. It is presumed to inhabit forested areas and be terrestrial like other members of the Oligodon genus. Species in this genus are generally found in forested areas, though exact details for O. annamensis remain unknown.

Behaviour and ecology:

Lifestyle:

Oligodon annamensis is presumed to be nocturnal, like other species of its genus. These snakes are often terrestrial and are known to feed on small vertebrates, such as lizards, frogs, and small rodents. Many Oligodon species are also oviparous, laying eggs in hidden areas such as under leaf litter or logs.
Reproduction:

The species is presumed to be oviparous, as this reproductive strategy is common in the genus Oligodon. However, no specific details are available about its reproductive behavior, clutch size, or seasonality.

Conservation and status:

IUCN Red List Category and Criteria:

Data Deficient (DD) due to the lack of sufficient information on its population, habitat preferences, and potential threats.
Population Trend:

The population trend is unknown, as the species has been observed only from a few specimens, and recent sightings remain sparse.
Threats:

Specific threats to Oligodon annamensis are not well identified. However, habitat loss due to deforestation and agricultural expansion may be potential threats, as they are for many forest-dwelling species in Southeast Asia.
Conservation Actions:

Due to the lack of data, no targeted conservation measures are currently in place for Oligodon annamensis. Further research is needed to determine its distribution, population trends, and ecology in order to develop appropriate conservation strategies.
