二名法 Eurypharynx pelecanoidesVaillant, 1882 吞鳗（学名：Eurypharynx pelecanoides），又称宽咽鱼，吞噬鳗，咽囊鰻、大嘴鰻、闊嘴鰻、巨口鰻等，是輻鰭魚綱囊鰓鰻目寬咽魚科的一個种，是较少见的深海鱼类，偶见于捕鱼网误捕。吞鳗很类似于鳗类，与鳗鲡目的真鳗联系上较为紧密；現在已知的種類僅此一屬一種（Eurypharynx pelecanoides Vaillant, 1882）。其屬名是以 eurys（拉丁文：長）+ pharynx（希臘文：喉頭）構成，即“長喉嚨”之意。 吞鳗分布於全球各大洋水域。已知生活的水域深度約 500 至 7625 公尺。 辨識特征 吞鳗最显著的特征是它巨大的嘴，甚至大过它的身体。它的口部较松得绞合在一起，在必要的时候能够打开很大的角度以吞下比它大的食物。由于它的下颚部分外观与鹈鹕的喙很类似，所以在英语中吞鳗也被称为鹈鹕鳗（pelican eel）或伞口吞噬鳗（umbrella mouth gulper）。吞鳗没有肋骨，因此它的胃可以扩张以容纳体积巨大的食物。吞鳗依靠一条鞭装的长尾来行动。长尾末端可以发光，被认为可以用来吸引猎物。鳃孔小，与吻端距离长于与肛门的距离。鳃条骨数5，内脏游离骨数6。由于生活在深海，视力亦不发达。一般可以成长到 0.35 到 1 公尺长。 生態習性 吞鳗以甲殼類、魚類、頭足類、浮游生物為主食。由於眼小，多以側線系統來追捕餌食。性成熟時，雄性外型有一定的改變，雌性則無。 參考資料 Nielsen, Jørgen G.; E.

The pelican eel (Eurypharynx pelecanoides) is a deep-sea eel. It is the only known member of the genus Eurypharynx and the family Eurypharyngidae. The species belongs to the "saccopharyngiforms", members of which were historically placed in their own order, but are now considered true eels in the order Anguilliformes. The pelican eel has been described by many synonyms, yet nobody has been able to demonstrate that more than one species of pelican eel exists. It is also referred to as the gulper eel (which can also refer to members of the related genus Saccopharynx), pelican gulper, and umbrella-mouth gulper. The specific epithet pelecanoides refers to the pelican, as the fish's large mouth is reminiscent of that of the pelican.
