Okay kiddo, so snakes have venom inside their bodies which can be dangerous for people and other animals if they get bitten.
Venom is made up of special chemicals that can hurt other living things when they come in contact with it. Some snakes use venom to catch their food, while others use it to defend themselves if they feel threatened.
When someone gets bitten by a venomous snake, the venom goes into their body and can cause different reactions. Some common symptoms are swelling, pain, and a feeling of sickness. But if the venom is very strong, it can make someone really sick or even cause their body to stop working properly.
So it's really important to stay away from snakes you don't know, and to be careful when you're around ones that you do know about. And if you or someone you know gets bitten by a snake, it's very important to get medical help right away.
