Tuatara are found only on New Zealand islands and are considered living fossils. They also communicate acoustically. Acoustic communication is not only widespread in land vertebrates like birds and mammals, but also in reptiles, amphibians and fishes. Many of them are usually considered mute, but in fact show broad and complex acoustic repertoires. According to researchers at the University of Zurich, the evolutionary origin of vocal communication dates back more than 400 million years. The use of vocalizations as a resource for communication is common among several groups of vertebrates: singing birds, croacking frogs or barking dogs are some well-known examples. These vocalizations play a fundamental role in parental care, mate attraction and various other behaviors.
