台灣東部秀姑巒溪民多羅龍口蛇鰻

The Mindoro Snake Eel Lamnostoma mindorum (Jordan and Richardson) of the Hsiukuluan River in the Eastern Taiwan

The Mindoro snake eel Lamnostoma mindorum (Jordan and Richardson, 1908) in the Hsiukuluan River of the eastern Taiwan occurred in the winter and early spring seasons of low water flow, and had two age classes at the modes of 34-37 cm and 46-49 cm in total length (juvenile and immature adult). These provided additional evidences to its rarity in freshwater near the mouth of rivers that the Mindoro snake eel is a peripheral freshwater fish defined as one that lives and spawns in ocean but some of its individuals occasionally intrude into freshwater streams. 台灣東部秀姑巒溪民多羅龍口蛇鰻（Lamnostoma mindorum）為周緣性淡水魚，於冬天至春天低流量時偶然進入淡水河口，體長分兩群34-37 cm及46-49 cm，代表兩年齡群，在河內覓食底棲魚蝦。
