This snake will bite but is harmless as it lacks venom, usually found along the margins of rainforests and in open forest areas where it preys on small reptiles and amphibians. It is even known to eat young toads safely. The brown to olive-green body has indistinct darker cross-bands and there are some pale flecks present, belly is cream.
