The Olive House Snake (*Elaiophis inornatus*) is a master of understated elegance, often overlooked by those seeking flashy patterns, but a favorite among seasoned herpetologists for its silky texture and docile nature.
Identification
This is a robust, medium-sized serpent, typically reaching 75–130 cm. As its specific name *inornatus* suggests, it is "unadorned." The dorsal color is a uniform, glossy olive-green to dark slate-grey or even blackish-brown. To distinguish it from the common Brown House Snake (*Boaedon capensis*), look at the head: the Olive House Snake lacks the characteristic pale stripes running through the eye. Its belly is a striking, clean creamy-white or pale yellow, and its eyes have vertical, cat-like pupils—a classic hallmark of a nocturnal hunter.
Habitat & Range
Endemic to Southern Africa, this species favors high-rainfall regions. You’ll find them tucked away in the moist savannahs, grasslands, and fynbos of the Eastern Cape, KwaZulu-Natal, and Mpumalanga. They are particularly fond of "mist-belt" forests and are frequent visitors to suburban gardens where damp rockeries provide the perfect refuge.
Behaviour
Strictly nocturnal, this snake emerges at dusk with a slow, deliberate movement. While many snakes strike when cornered, the Olive House Snake is remarkably placid, rarely biting even when handled. They are terrestrial but capable climbers. During the breeding season in early summer, females lay clutches of 6–15 elongated eggs in decomposing organic matter, which provides the necessary warmth for incubation.
Diet
A powerful constrictor, its diet is primarily mammalian. It specializes in raiding the burrows of rodents and shrews, though it will occasionally take fledgling ground-nesting birds or lizards.
Fascinating Fact
Despite its "plain" name, the Olive House Snake possesses a breathtaking structural iridescence. When caught in the right light, its dark scales shimmer with a distinct "mother-of-pearl" oily sheen, much like a spilled drop of gasoline on water!
