Etymology: Neobythites: Greek, neos = new + Greek, bythitis, -idos = it is at the bottom, sunken (Ref. 45335); elongatus: From the elongate form of the body (Ref. 40522). More on authors: Nielsen & Retzer.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 230 - 1270 m (Ref. 34024). Deep-water
Western Atlantic: Florida Strait to off Panama.

Morphology | Morphometrics
soft rays: 86 - 90. Dorsal part of the body with marbled, brownish pigmentation, but lacking ocelli and stripes. Hind margin of preoperculum with 2 spines. Pseudobranchial filaments 2-4. Teeth granular. Ventral fin rays far from reaching anus, 12-14% SL (Ref. 40522).
Common species (Ref. 34024) found to feed on small gastropods and crustaceans (Ref. 32505). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
