[1][2] It is a limbless lizard[2] found burrowing in loose soil in arid areas.

[3] The preferred natural habitats of A. haroldi are coastal sand dunes and sandy desert.

Both dorsally and ventrally, A. haroldi is pale brownish grey with darker markings, except for the lips and chin which are yellowish white, and the underside of the tail which is creamy white.
