Enamel, a hard, mineralized formed by ameloblasts prior to tooth eruption, coats the coronal portion of the tooth. Siamangs are notable for having more coordination and contact during daily activities. breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female. They are remarkably active and agile brachiators, capable of exceeding 3m in a swing. In addition to extra-pair copulations, pair-bonded gibbons occasionally "divorce". From Chinese cultural influence, the Zen motif of the "gibbon grasping at the reflection of the moon in the water" became popular in Japanese art, as well, though gibbons have never occurred naturally in Japan.[44].
