Venomous snakes are a group of snakes that can inject venom through their bites. This venom is a special fluid that helps them catch prey and defend themselves. Some well-known examples of venomous snakes include the King Cobra, Rattlesnake, and Black Mamba. Their venom can vary in strength, with some being deadly to humans while others may cause only mild symptoms. These snakes use their fangs to deliver venom, which can affect the nervous system or blood. It's important to be cautious around them, as their bites can be dangerous. However, many venomous snakes play a vital role in their ecosystems by controlling rodent populations and maintaining balance in nature.
