Question

Quizplus · Accepted Answer

A bobbing dewlap in a lizard is a signal, used to communicate with other individuals or potential mates. It is not a reflex, as it is under conscious control of the lizard. It is also not an innate releasing mechanism, which is a fixed, stereotyped behavior triggered by a particular stimulus. Additionally, a dewlap is not necessary for respiration.
