Naja

Naja is a genus of venomous snakes commonly known as cobras. They are notable for their ability to flare a distinctive hood behind their heads when threatened, as a warning display. Najas species vary in size and habitat, but many are found in Africa and Asia. Their venom is a mix of toxins that can affect the nervous system, and they primarily use it to subdue prey like small mammals, birds, or reptiles. Despite their dangerous reputation, cobras generally avoid humans and will only bite defensively. They play an important role in controlling pest populations in their ecosystems.
