How do lizards communicate?
----------------------------------------------------------------------
Lizards in the suborder Iguania communicate by doing push-ups and
other athletic displays. They convey territoriality, courtship
displays, and other messages with various combinations of push-ups,
body postures, head movements, and displays of colorful belly patches
or throat dewlaps.
The Iguania includes the common sagebrush lizards of the American
west, as well as iguanas and tropical anoles. Different species have
different languages, and within each species there may be regional
"dialects."
A recent study showed that, like the languages of humans and some
kinds of birds, lizard body language is an open grammatical system.
This means that they can express many different messages using a
fixed set of symbols combined in various orders.
