Amphisbaena alba is widespread in South America and has been described as common in parts of its wide range. It can be found in a wide variety of habitats including altered and disturbed habitats and so has been assessed as Least Concern.

Geographic Range [top]

Range Description:This species has a very large distribution, perhaps the widest distribution of any amphisbaenian (Colli and Zamboni 1999). It is found in most of South America, east of the Andes, but not the far south of the continent.
Countries occurrence:
Bolivia, Plurinational States of; Brazil; Colombia; Ecuador; French Guiana; Guyana; Panama; Paraguay; Peru; Suriname; Trinidad and Tobago; Venezuela, Bolivarian Republic of

Population [top]

Population:In the Amazon region of Brazil it is a common reptile, but its burrowing habits and the fact that it is rarely encountered above ground gives a misleading impression of rarity (Lainson 2003). This species has been found above the surface.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in a variety of natural habitats including savanna and rainforest, as well as in altered cultivated or forested areas.

Threats [top]

Major Threat(s): It is unlikely that any major threat is impacting this species across its wide range. Amphisbeanians may be less susceptible to the vagaries of climate than other squamates that live above ground, because the subterranean habitats may act as a buffer (Colli and Zamboni 1999).

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place or needed for this species.
