 Lizards communicate by doing
push-upsand other athletic displays. They convey
territoriality,
courtshipdisplays, 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.
