The length and arrangement of the auditory hairs in the inner ears of snakes appears to be fairly uniform across species, at least relative to the variation seen in lizards, which can have very different auditory hair anatomy among families and often even among closely-related species. Peripheral hearing mechanisms in reptiles and birds (Vol. Your email address will not be published. and for the snake to 'hear' the vibrations, its head must be on the ground. 26). Eventually, the weaker snake will be driven away, leaving the stronger male to mate with the female. Journal of Experimental Biology 54:349-371 <, Ito, R., & Mori, A.

They may decide they need to retreat or that they need to be ready to be defensive should that movement continue into their direction. The use of ground-borne vibrations for prey localization in the Saharan sand vipers (, Young, B. Almost all snakes can make a hissing noise by forcing air out of their glottis (the end of the trachea). All reptiles have the ability to hear, albeit, to different degrees. Nevertheless, snakes can better perceive low-frequency sounds. They provide other snakes with key information, such as the snake’s age, sex, and if she’s ready to mate.
