How to Identify the Angola Green Snake (Identification Guide)

Key identifying features

The Angola green snake (Philothamnus angolensis) is identified by its bright green, unmarked body, slender build well suited to climbing, and prominent large eyes typical of arboreal, day-active colubrid snakes in the genus Philothamnus. Its uniform green color without strong pattern is the most immediate visual clue.

Coloration & pattern

The body is typically bright to medium green above, sometimes with a slight yellowish or bluish tinge, and generally lacks bold blotches, bands, or spots, appearing largely uniform along its length. The underside is usually paler green, yellowish, or white, contrasting mildly with the darker green back. Some individuals show fine dark edging along individual scales, giving a subtly reticulated look on close inspection.

Head, eyes & scales

The head is narrow and only slightly distinct from the neck, with a rounded snout. The eyes are large and prominent with round pupils, an adaptation shared with other actively hunting, visually oriented green snakes. Scales are smooth, keeled scales are absent, contributing to the snake's glossy appearance.

Size & body shape

Adults typically reach 2.5 to 4 feet, with a slender, laterally compressed body and long tail well adapted for climbing through shrubs and trees. The body is markedly thinner than that of most ground-dwelling snakes of similar length.

Range & habitat where you'll see it

The Angola green snake occurs across parts of south-central Africa, including Angola, Zambia, and neighboring areas, favoring woodland, forest edge, and shrubby vegetation, where it spends much of its time climbing among branches and foliage in search of frogs, lizards, and other small prey during the day. <br>

How to tell it apart from look-alikes

Several other Philothamnus green snake species occur across Africa and can look quite similar, so precise identification often depends on subtle scale counts or range, but the combination of uniform green color, slender arboreal build, large eyes, and a Central African range help narrow identification to this species or its close relatives. Non-venomous green colubrids of this type are generally distinguished from unrelated green snakes elsewhere in the world simply by range, since true green tree-dwelling colubrids of this pattern are largely restricted to Africa.
