The Javan torrent frog (''Huia masonii'') is a species of frog in the Ranidae family. It is endemic to Java, Indonesia. Its natural habitats are clear, fast-flowing streams and torrents in forests and in somewhat more open areas. It is a common species within this specific habitat, which is being threatened by sedimentation of streams as well as agro-chemical pollution.〔 Javan torrent frog males use high-frequency communication to overcome the noise of their riverine habitats that is dominated by low frequencies. The second harmonic of the calls is ultrasonic. Warbles are highly diverse and may function as vocal signatures. ==See also== * Concave-eared Torrent Frog (''Odorrana tormota''), the first frog demonstrated to both produce and perceive ultrasonic frequencies * Hole-in-the-head Frog (''Huia cavitympanum''), a truly ultrasonic frog ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Javan torrent frog」の詳細全文を読む スポンサード リンク
