What is a physical feature of a cobra?

A physical feature of a cobra is the distinctive hood used for territorial purposes, mating and attacking. When the hood is not in use, it is limp and pressed closely to the snake’s body. Though it serve no practical funtion, the hood displays aggression and is useful for courting.

Whenever a cobra feels intimidated, the snake creates a slender hood by flexing their ribs and surrounding their necks with excess skin. The hood offers an illusion of a larger body, which is useful for mating and preventing potential danger. In addition to the hood, the cobra typically raises its body off the ground.
