Which venomous species is often mistaken for the Rhombic Egg Eater in regions like South Africa?

The Night Adder (Causus species), a venomous viper that can cause fatal misidentification.

Confusion between the harmless Rhombic Egg Eater and genuinely dangerous reptiles poses a risk, particularly in areas where they coexist, such as South Africa. The Night Adder, belonging to the viper family, is frequently mistaken for *D. scabra*. While visual cues like head shape or pupil structure might differ upon close inspection, rapid or distant observation, especially under poor lighting conditions, can lead to incorrect identification. This mistake is dangerous because the Night Adder possesses venom, unlike the egg-eater, emphasizing the importance of accurate identification when encountering snakes exhibiting alarming behavior.
