The Naja, commonly known as the cobra, is a genus of venomous snakes found primarily in Africa and Asia. Cobras are known for their distinctive hood, which they can expand when threatened. They are highly adaptable and inhabit a variety of environments, including forests, grasslands, and deserts. Cobras are famous for their potent venom, which they use to immobilize prey such as rodents and birds. Some species, like the Indian Cobra and King Cobra, are well-known for their size and striking appearance. Cobras play a crucial role in their ecosystems as both predators and prey.
