Do today's Reptiles communicate with sound?

[Alek]

So I am watching Dino Dan on Nick Jr with my son :), and they had a segment that Dinosaurs communicate with sound. Is there any reptiles today that do this? Now I know birds do? I also know that Tegus do a snort type sound when they see me or other tegus, are they chatting or sending some type of signal?

All crocodilians are quite vocal, and many have some amazing displays that utilize sonics. Geckos are unique among lizards in that they actually possess vocal cords, the nocturnal geckos particularly are acoutistic. Some tortoises, particularly those of the genus Chelonoidis have mating calls. But aside from general warning hisses or snorts, there isn't much in the way of auditory communication in any other reptiles.

That is right the geckos make a "cak" like sound. And Crocodilians roar, or mutter right?

From my experience so far with my tegu I have noticed little sounds, other than the hissing and snorting, coming out of his mouth when he/she looks at me and it is really cute. It SEEMS to be a form of communication... unless it is just wishful thinking on my part. 8)

I do think that they can communicate with sounds. When they were little and I picked them up they made a squeaking sound. It was funny. They haven't done it since a long time.

But How else would they communicate though? Now I'm all curious haha

[txrepgirl]

Body language. Like some lizards bob their head, wave their hand, move their tail in a certain way.

[Calypso]

That does make sense. I feel surprisingly dumb haha

[txrepgirl]

It's OK. Please don't feel dumb. I know you knew about this. You just didn't remember or think of it at this time. It happens to all of us ;) .

They have a surprising social network and system of communication. I think Igs have cornered the market on reptile communication. Tegus do make little huffs, bigger huffs to signal courting interest or warning. They arch their backs, tail wiggle, lift and lower heads. OK, that's not sound, but cool to watch.

I think crocs and geckos have the best sound signals. My little female crested gecko would shake her head and say, "Nooooooo" whenever the male got close. Needless to say, she never produced viable eggs for me. haha
