I just thought I would let you know and thank you for dedicating so much of your time to snakes. Snakes are adapted to hear only low-pitched sounds. Although cobras can hear, they are actually deaf to ambient noises, sensing ground vibrations instead. Heterospecific alarm call eavesdropping in nonvocal, white-bellied copper-striped skinks. Snakes have a hearing range of 80-600 Hz, although some species can hear up to 1000 Hz. burrowing snakes have the longest papillae, arboreal snakes the shortest, and terrestrial snakes have papillae of intermediate length. Snakes usually prefer to live alone, but they still need to ‘talk’ to each other in their own unique way. I mentioned you in the first one and referenced your blog.

I'm still curious to know why those snakes which react adequately well to visual stimuli give me the impression, or simulate, that they are completely deaf. Amphisbaeneans have lost more of their airborne sound detection capacity than most burrowing lizards, in that, like snakes, they have also lost their tympanum and have their columella connected directly to their lower jaw (some naked mole rats have a similar jaw-middle ear connection and rely heavily on vibrational communication). A. Why Do Snakes Musk? 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. One of my followers watched the video and subsequently sent me a fantastic recording of how our voices might sound to snakes based on their possible hearing range.

Instead, they use their forked tongue. Snakes can hear, but only very low frequencies and these are more along the lines of vibrations from footsteps and the low bass from a speaker system. Snakes deposit them on the ground, although some have also been found to be airborne, according to research published in Biology Letters. So, snakes communicate with other snakes out of necessity.

A few decades ago the answer was no, for - obviously - snakes don't have external ears. The chemical makeup of the pheromones changes as the snake ages, and becomes sexually mature. Given that the average human voice is around 250 Hz, snakes can actually hear us talk.

However, research suggests that snakes cannot hear each others’ hissing sounds. But snakes don’t “sniff out” pheromones using their nose. It's possible that some of these muscles move the columella away from the quadrate during feeding, but it doesn't seem that anyone's looked. This fools other males into trying to mate with them, distracting them from the true female. Specifically, they are deaf to sounds that travel through the air.
