What is the sound made by a type of poisonous snake?

Poisonous snakes, such as rattlesnakes, produce a distinctive sound known as rattling, created by the rapid vibration of their tail segments. This sound serves as a warning to potential threats, signaling their presence and venomous nature. Other poisonous snakes, like vipers, may hiss or make a similar warning sound, but the rattling is specific to rattlesnakes.
