What feature distinguishes the subgenus Uraeus, to which Naja nivea belongs?
Answer
It groups the African non-spitting cobras
The subgenus *Uraeus* serves to partition the genus *Naja* based on evolutionary divergence and specific behavioral traits, particularly venom delivery methods. *Naja nivea* is explicitly placed within *Uraeus* because this grouping specifically collects the African cobras that lack the specialized capability to eject or spit venom. This distinction is crucial taxonomically, separating them from cobras in other subgenera, such as the Asiatic cobras sometimes classified under *Naja*, which may utilize spitting as a primary defense mechanism. The absence of spitting capability reflects a key difference in evolutionary trajectory within the *Naja* lineage.
