Etymology: Apteronotus: Greek, apteros = without wings / (in this cases, fins) + Greek, noton = back (Ref. 45335);  acidops: The latinized epithet acidops is compounded by the Greek words akidos meaning "point" and ops meaning "face", referring to the very elongated and pointed head morphology of the species.

Environment: milieu / climate zone / depth range / distribution range Ecology

Short description Morphology | Morphometrics

Anal soft rays: 162 - 220. Distinguished from other congeners by the following combination of characters: dorsal snout profile pointed; snout length 46.4 - 63.7 % of head length; oculo-nasal distance 39.2-72.1 % of postocular distance; lateral ethmoid with both dorsal and ventral extremities expanded, strongly oblique in orientation; mouth rictus surpassing vertical through anterior eye margin, including its skin folds, in all ages; dorsal head profile nearly horizontal from a vertical through anus to posterior extremity of occipital bone; absence of mid-dorsal white or clear stripe on head and body anteriorly; chin brown; upper lip clear to a vertical through anterior nostril; transversal unpigmented bar or bars posteriorly on the body absent; flanks brown, darker dorsally and pectoral fin hyaline, with chromatophores over rays (Ref. 88927).

Biology     Glossary (e.g. epibenthic)

Length type refers to length to the end of anal fin, LEA (Ref. 88927).
