Which species of cobra is mentioned as an example of a species that threatens or bites but does not project venom like *N. nigricincta*?
Answer
Egyptian Cobra (*Naja haje*)
The text uses the Egyptian Cobra (*Naja haje*) as a specific contrast point when detailing the defensive divergence among cobras. While *N. haje*, like all cobras, employs the classic intimidation tactic of displaying its hood to visually exaggerate its size, it relies on threatening postures or biting for defense rather than actively projecting venom in a directed stream. This contrasts sharply with the adaptations found in spitting lineages like *N. nigricincta*, which have evolved an active, ranged chemical deterrent alongside the traditional hood display.
