Geckos are lizards found in warm climates throughout the world. They range from 1.6 to 60 cm. Geckos are unique among lizards in their vocalizations in that they use chirping in social interactions. The New Latin gekko and English "gecko" stem from the Indonesian-Malay gēkoq, which is imitative of the sound they make.
