Etymology: Ophidion: Diminutive of Greek, ophis = serpent (Ref. 45335); antipholus: Named for the brothers Antipholus (Shakespeare's The Comedy of Errors), whose identities were confused throughout the play; noun in apposition. More on authors: Lea & Robins.

Morphology | Morphometrics
soft rays: 94 - 103;
Vertebrae: 65 - 69. This species is characterized by the following features: D 111-133 (usually 116-123); A 94-103; pectoral fin rays 18 or 19 (rarely 20 or 21); precaudal vertebrae 15-17 (usually 16), caudal vertebrae 49-53 (usually 50-52), total vertebrae 65-69 (usually 66-68); lower arm of first gill arch with 5 or 6 developed rakers; rounded head profile with mouth distinctly inferior; dorsal and ventral profiles of body nearly parallel for much of its length; unmarked body; short and unequal pelvic-fin rays, longer reaching to point directly under anterior edge of opercle (Ref. 81834).
Observed on open sand and mud bottoms (Ref. 81834). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
