How to Identify the Green Bush Viper (Identification Guide)

Key identifying features

The Green Bush Viper is a compact, heavily built arboreal viper well adapted for climbing through shrubs and low trees, using a moderately prehensile tail for grip. It typically remains coiled among foliage, relying on camouflage rather than movement to avoid detection. Its combination of vivid green coloring, rough scale texture, and broad viper head shape make it identifiable once these features are noted together.

Coloration & pattern

Coloration is usually a bright to olive green, sometimes with individual scales edged in yellow, black, or blue creating a subtly speckled or scalloped look across the body. Some individuals show faint darker chevron-like markings along the back, though these can be difficult to see against the green background. The belly is generally paler green or yellowish, often plain.

Head, eyes & scales

The head is broad and distinctly triangular, well separated from the neck, a defining viper trait, with vertical, slit-like pupils suited to primarily nocturnal activity. Dorsal scales are strongly keeled and often appear rough or bristly, giving the body a textured, almost spiny appearance that is one of the most useful tactile and visual identification features for this species.

Size & body shape

This viper has a thick, muscular body relative to its modest length, with a short, strongly prehensile tail adapted for gripping branches and vines. Its compact, heavy-bodied build supports a slow, deliberate ambush style of hunting from a coiled position among vegetation.

Range & habitat where you'll see it

The Green Bush Viper inhabits tropical forests, forest edges, and dense vegetation across parts of central and western Africa, typically remaining well above ground in shrubs, vines, and low tree branches. It is most active at night, when it may be found stretched along a branch waiting for passing prey, and is rarely encountered on open ground.

How to tell it apart from look-alikes

The broad triangular head, vertical pupils, and rough, heavily keeled green scales distinguish this species from harmless green tree snakes and vine snakes, which typically have narrower heads, round pupils, and smoother scales. Compared to other related bush vipers, subtle differences in scale edging color and precise range help with more detailed identification, but the general thick-bodied, rough-scaled viper form is a reliable first indicator. Its slow, deliberate movement and coiled ambush posture in vegetation further support identification alongside its coloring.
