A cobra is a type of snake known for its distinctive hood, which it can expand when threatened. These snakes are found in various parts of the world, especially in Africa and Asia. Cobras are famous for their venom, which they use to hunt prey and defend themselves. Some species, like the Indian cobra, are well-known for their role in traditional medicine and cultural practices. Cobras are fascinating creatures with unique behaviors. They can stand upright and "dance" when they feel threatened, making them a popular subject in snake charming. Despite their fearsome reputation, cobras play an important role in their ecosystems by controlling populations of small animals.
