Black Ghost Knife Fish 魔鬼刀/黑色幽靈魚 

The fish is all black except for two white rings on its tail, and a white blaze on its nose, which can occasionally extend into a stripe down its back. It moves mainly by undulating a long fin on its underside. It will grow to a maximum length of 50 cm (20 in)

Black ghost knife fish are nocturnal. They are a weakly electric fish which use an electric organ and receptors distributed over the length of their body in order to locate insect larvae.

牠的身體上沒有鱗片, 尾部有兩個白色的環狀條紋, 鼻子上的白色斑紋有些會延續到尾部. 因为沒有背鰭, 線翎電鰻會藉著擺動身體下側的旗狀魚鰭移動,泳姿優美且獨特。

身體下側的裙帶狀魚鰭,则能够使牠自在的向前、向後及垂直移動。
