Dewlap extension occurs alongside a number of behaviors exhibited by the brown anole, namely during courtship. [34] In an experiment by Richard Tokarz, an experimental group of male brown anoles underwent a surgery that rendered them unable to extend their dewlaps; a control group of male anoles were subject to the same surgery, but without the ...
Lizards have evolved several modes of communication, including visual, chemical, tactile, and vocal.
