What is the immediate purpose of the *Naja nigricincta*'s characteristic hood display?

To appear much larger and intimidate a perceived threat

The hood display is the initial and primary defensive posture adopted by the *Naja nigricincta* when it perceives itself to be cornered or directly threatened. This action involves the snake raising the anterior (front) portion of its body off the ground and spreading its neck ribs outward to form the iconic, flattened hood shape. This dramatic visual presentation serves the distinct purpose of making the snake appear significantly larger than its actual size. The goal of this intimidation tactic is to deter or frighten the perceived threat into retreating without necessitating the escalation to more severe defensive actions, such as spitting venom or biting.
