Overview
The Two-coloured Snake, also known as the bicolored quill-snouted snake, is a small fossorial species found in southern Africa. Its name refers to its characteristic pattern of contrasting dark and light body coloration.
It possesses a mild rear-fanged venom used to subdue small prey, but it poses no significant medical threat to humans and is considered harmless in practical terms due to its small size and reclusive habits.
How to identify it
- Body divided into two distinct color zones, typically a dark anterior and paler posterior, or vice versa depending on the population
- Elongated, cylindrical body adapted for burrowing
- Distinctive pointed, wedge-shaped snout used for pushing through loose soil
- Small eyes with round pupils
- Smooth scales typical of fossorial snakes
The sharply demarcated bicolored pattern combined with the pointed snout readily distinguishes it from other small burrowing snakes in its range.
Habitat & range
Found in sandy and loose soils across savanna and semi-arid habitats of southern Africa, including parts of South Africa, Namibia, Botswana, and Zimbabwe. It spends most of its life underground or beneath surface litter.
It favors friable substrates that allow easy burrowing and is rarely seen above ground.
Behavior, diet & reproduction
A secretive, fossorial species active mostly underground, emerging occasionally at night or after rain. It preys on other burrowing reptiles, particularly other snakes and legless lizards, subduing them with a mild venom delivered from rear fangs.
Reproduction is oviparous, with females laying small clutches of eggs typical of small burrowing snakes.
