Ears

I just learned that Chams don't have ears. They go by vision and vibrations. Anyone have any comments?
 
I know it's true, I always talk to my chams and play the stereo for them while I'm away, how dumb do I feel now.
 
I'm sorry but they're ears are auctually invisible and they dont want us to know that they have ears... Who knew :D
 
They lack external ears. Some species are capable of producing sounds/vibrations in infrasound (see Vibratory calls in true chameleons). I have not observed my cham to respond to noise (including thunderstorms, which I would think he would feel if not hear), but that doesn't stop me taking to him (or my husband leaving the radio on when we're not around).
 
That's good to know, I love talking to both of mine, it's like they sense what you're say. Maybe it's the body language, anyway they're my babies and I'll coo at them all day long. LOL
 
Well, they don't have external openings to a developed ear canal, but they can "hear" or feel low frequency vibrations. The buzzing or vibrating some species use to communicate is also low frequency sound. If you play music that's heavy in bass they could feel it. When they seem to react to you talking to them they are probably watching your lips and face move.
 
Chameleon ears...
"The observations indicated that aerial sounds are received by a special surface, the pterygoid plate, embedded in the tissues at the side of the head. This system resembles that of snakes, in which a detached quadrate bone serves as a receptive surface."...

"This pathway makes possible a mobilization of the cochlear fluids in response to sound pressures exerted at the oval window by the columellar footplate."...

"the presence of fluid in the "snail" and of tissue that acts as a tympanic membrane enables chameleons to detect frequencies from 200 to 600 Hz."...

And now for the vibrating/"hooting"...

oh wow, that last clip sounds like a frog! when i would hold my female dilepis, i could feel vibrations coming from her sometimes.
 
Even though we know they can't hear, my husband and I talk to our chams all the time. "How ya doin' you miserable old bag?", "Meh". Just for fun. It also makes the parrot jealous that we're not paying attention to her 100% of the day (she's only a few feet away).
 
"the presence of fluid in the "snail" and of tissue that acts as a tympanic membrane enables chameleons to detect frequencies from 200 to 600 Hz."...although this is a very narrow range compared to humans....its saying that they can still hear.
