Snakes 'hiss' - It sounds just like the sound humans make when they say the letter 'S' out loud. One of my favourite past-times is driving and exploring with my husband (and my dog). In WikiAnswers, I am constantly On the wallaby.
Snakes do not have especially keen senses of sight or hearing. They rely instead on special sense organs to provide them with information about their environment.ertain bones in a snake's head respond to sound waves and transmit them to the inner ear. A snake's tongue has few taste buds. It is used with an organ of smell called the Jacobson's organ, which, along with the nostrils, provides snakes with a keen sense of smell.
