Reptile brains respond to music

[Catherine]

I agree with you, snakes have excellent hearing. External ears are not needed for sound to be transmitted. 
My snakes respond to my voice. If they know someone they will respond to that voice. If I have a stranger in the house they are less likely to respond. 
Music is different. We recognize the patterns in it. For a reptile it would be different. I think my snakes are fine with the background sound of the radio and a human voice. I would want to play different types of music and see how they respond. Music wouldn't be the same for them as for me, but they might like certain types of sounds better than others.  I don't think they would like jarring sounds. Probably very loud music would not be to their liking.

You are right about the heat sensing. I was generalizing. The rat snakes see very well, but it is different from our type of vision. 
They can dislike something I have added to a tank as decoration and I will have to remove it. They are very fussy about their environment. I find the ball pythons respond to heat sources. I have to warm their food if I want them to find it.  Corn snakes not only see the food they are a good judge of size. They don't eat something too big for them. 

It makes sense that a brain similar to a birds would respond to music. Music is important to birds. They use song for communication. I don't know if we have a way of gauging the emotional response of a crocodile to music. It certainly wouldn't be the response that we have. It is an area that needs more study.
