Facultative air-breathing (Ref. 126274); Adults inhabit mainly clear streams, often deeply shaded and relatively fast-flowing, although it sometimes occurs in lakes, particularly in Tasmania. In New Zealand and parts of Tasmania, juveniles occur in marine waters, presumably the larvae are washed out to the sea. The existence of a marine stage is regarded to be facultative rather than obligatory in Australia. They swim near the bottom, usually around the cover of rocks and logs. More common in uploads (Snowy Mountains, Otway Ranges, central Tasmania) than at lower elevations (Ref. 44894).
主要棲息於清澈溪流, 時常深深地遮蔽與相當快速流動的, 雖然它有時出現於湖中, 特別地在塔斯梅尼亞。 在紐西蘭與塔斯梅尼亞的部份中，稚魚出現在海洋,仔魚被沖刷到海洋可能。 海洋階段的生存被視為是官能性而不是必須的在澳洲。
