Analysis of 36 records of the rarely encountered moray Gymnothorax polyuranodon indicate that juveniles and adults inhabit fresh and mildly brackish habitats (salinity < 5) in streams of the Australian Wet Tropics Eighty-one per cent of these records were from freshwater streams and collectively demonstrate that this species inhabits fresh water throughout all seasons. A survey of fish researchers, each with at least 100 h of field experience in Australia's Wet Tropics, revealed that 33% of researchers working in fresh waters (nine of 27 researchers) had encountered the species and 15% of researchers with substantial experience working in estuaries (two of 13 researchers) had encountered the species. The species was not sampled or observed in the nearshore marine environment. The only record of an elver of this species was, however, found in an estuary at a salinity of 33·4. This preliminary evidence suggests adult G. polyuranodon occupy freshwater habitats, but further research is required to understand the complete life cycle, including movements, habitat use and reproductive ecology of the species.
对 36 份罕见的波纹裸胸鳝 Gymnothorax polyuranodon 记录进行分析表明，幼鱼和成鱼栖息在澳大利亚湿润热带地区溪流中的淡水和微咸栖息地（盐度<5）。这些记录中有 81%来自淡水溪流，这表明该物种在所有季节都栖息在淡水中。一项针对鱼类研究人员的调查显示，每位研究人员在澳大利亚湿润热带地区都有至少 100 小时的实地经验，结果发现，在淡水工作的研究人员中有 33%（27 名研究人员中的 9 名）遇到过该物种，在咸水河口工作的经验丰富的研究人员中有 15%（13 名研究人员中的 2 名）遇到过该物种。该物种在近岸海洋环境中没有被采样或观察到。然而，在一个盐度为 33.4 的河口发现了该物种的一个幼鳗记录。这初步表明成年波纹裸胸鳝栖息在淡水栖息地，但需要进一步研究来了解该物种的完整生命周期，包括其洄游、栖息地利用和繁殖生态。
