Rhinoplocephalus

Rhinoplocephalus is a small genus in the family Elapidae, the front-fanged snake group that also includes cobras, sea snakes, and the many small terrestrial elapids of Australia. It is a minor member of that radiation, represented in this database by a single species, the Square-nosed Snake (Rhinoplocephalus bicolor). Like its relatives, it is a fixed front-fanged snake, but it is a small, slender, nocturnal burrower rather than anything resembling the large, conspicuous elapids most people picture. Australia is unusual in that elapids dominate its snake fauna, and Rhinoplocephalus sits among the many compact, ground-dwelling members of that group.

The genus is Australian, with the Square-nosed Snake occurring in the southwest of Western Australia. Members favor sandy and heath habitats and spend much of their time hidden beneath leaf litter, logs, loose soil, and surface debris, emerging at night. In general terms, snakes in this group are small and smooth-scaled with a narrow head that is not strongly distinct from the neck, and a bluntly squared or wedge-shaped snout suited to pushing through loose ground. Coloration tends toward muted browns and dark tones that match the soil and litter where they live. Because identification of small Australian elapids is genuinely difficult and several look-alike groups overlap, any small dark snake in this region should be treated as potentially venomous and identified by a qualified expert rather than by eye.

As an elapid, this is a venomous genus, and no venomous snake should be handled in the wild. That said, the Square-nosed Snake is a small, secretive species that poses little practical threat to people and is not considered dangerous in the way the large Australian elapids are. Its diet centers on small reptiles, especially skinks and other lizards encountered while foraging at night, and like many small Australian elapids it is believed to give live birth rather than lay eggs. Behaviorally it is shy and fossorial, relying on cover and concealment rather than confrontation. If a bite from any Australian elapid occurs, treat it as a medical emergency: apply pressure immobilization where trained to do so, keep the person still, and contact local emergency services immediately, or in the United States call Poison Control at 1-800-222-1222.
