 Lizards 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.
Different species of lizards 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.
