* Hisses: These are produced by forcing air through their nostrils.
* Rattles: Some snakes, like rattlesnakes, have a rattle on their tail that they shake to warn predators.
* Vibrations: Some snakes vibrate their bodies to create a buzzing sound.
* Chemical signals: Snakes communicate with each other through pheromones, which are chemicals released into the environment.
While snakes don't bark, some species can make sounds that resemble grunting or growling.
