The normal lizards that you might see in your house are harmless. Different researchers using the same model of transmitter may select reduced signal strength to increase battery life if the focal species is not wide-ranging; thus there was substantial variation in signal range and battery life among research projects.109 Knapp and Owens111 conducted radio telemetry on hatchling Andros Iguanas (Cyclura cychlura cychlura) by placing transmitters on the dorsal side of the pelvic girdle with test monofilament line wrapped around the lizard’s body to secure it.
