why do lizards bark loudly

·1 min read

The Short AnswerLizards don't bark like dogs. Their vocalizations are typically hisses, clicks, or chirps, not loud barks. These sounds are used for communication, such as warning rivals, attracting mates, or signaling danger to other lizards.

The Science Behind It

While the term 'barking' is usually associated with canids, some lizards do produce sounds that might be described as rough or loud vocalizations. These are generally not true barks but rather specialized hisses, clicks, or guttural noises. For instance, the male Tokay gecko is known for its aggressive, loud 'barking' calls, which serve to defend territory and attract females. Other species, like certain iguanas or monitor lizards, might hiss loudly when threatened or make clicking sounds during courtship rituals. These sounds are produced by expelling air forcefully through their mouths or specialized vocal structures, distinct from the complex vocalizations of mammals. The purpose is primarily communication within their species.

Fun Facts

  • The Tokay gecko's 'bark' is one of the loudest and most distinct vocalizations among lizards.
  • Many lizards primarily rely on visual cues and body language for communication rather than sound.
