The gargoyle cusk (Xyelacyba myersi) is a species of cusk-eel from the subfamily Neobythitinae of the family Ophidiidae.

This species grows to a length of 57 centimetres (22 in) TL.

[1][2] The specific name honours George S. Myers (1905-1985) of Stanford University who taught the describer, Daniel Cohen, ichthyology.

[3] It is a rare benthopelagic fish which occurs at depths of 984–2,500 metres (3,228–8,202 ft) around the world, other than the eastern Pacific, in tropical and subtropical latitudes.

[4] The larvae are similar in overall form to the related bony-eared assfish, but have the 1–4 and 15–20 pectoral-fin rays elongated.
