Etymology: Ophidion: Diminutive of Greek, ophis = serpent (Ref. 45335); imitator: From the latin 'imitor' meaning to mimic or resemble, in reference to its striking resemblance to Lepophidium pardale and, to a lesser degree, Otophidium indefatigabile (Ref. 26886).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 18 - 112 m (Ref. 26886). Tropical
Eastern Central Pacific: off the tip of Baja California and Sinaloa, Mexico to the Gulf of Panama.

Morphology | Morphometrics
soft rays: 112 - 139;
Vertebrae: 70 - 76. Dark brown to black blotching and spotting on head, dorsal, and lateral portion of the body. Scales with anguilliform arrangement on body; ethmoid spine blunt. Pelvic filaments long. Gill rakers numerous. Prejuvenile stage present.
Uncommon species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
