### Identification The Boomslang is a master of mimicry and elegance. Reaching up to 1.5 meters, its most striking feature is its massive, emerald-green eyes with round pupils—the largest of any African snake relative to its head size. This gives them an almost "curious" expression. Look for an egg-shaped head and heavily keeled (ridged) scales that give the body a rough texture. Coloration is highly dimorphic: males are often a vibrant, electric green with black-edged scales, while females are a cryptic, earthy brown. To distinguish it from the Green Mamba, look for the Boomslang’s distinct "frown" created by prominent scales above the eyes and its lack of the Mamba’s coffin-shaped head.
### Habitat & Range This species is a true arboreal specialist, found throughout sub-Saharan Africa, excluding the hyper-arid deserts. They thrive in a variety of biomes, from coastal thickets and moist savannas to Karoo scrub and high-altitude woodlands. You are most likely to spot one draped over a branch in an acacia or marula tree, where its slender profile blends perfectly with the canopy.
### Behaviour Diurnal and incredibly shy, the Boomslang is the "ghost of the trees." It spends its days gliding through branches with fluid grace. If you encounter one, it will likely freeze or vanish into the foliage. However, when cornered, it performs a spectacular threat display: it inflates its neck to twice its normal size, revealing dark skin between its scales. While it possesses a lethal hemotoxic venom, it is exceptionally docile and rarely bites humans unless handled.
### Diet A specialized hunter of the heights, the Boomslang’s primary prey is the chameleon. It stalks these lizards with agonizing patience, moving so slowly it mimics a branch swaying in the wind. It also frequently raids the hanging nests of weavers to consume chicks and eggs, using its rear fangs to deliver venom that prevents the prey from struggling.
### Fascinating Fact The Boomslang possesses incredible jaw flexibility; it can open its mouth to a staggering 170 degrees. This allows this rear-fanged snake to effectively "hook" its fangs into prey or a defensive target as easily as a front-fanged cobra!
