Etymology: Neoepinnula: Greek, neos = new + Latin ex = outside + Latin, diminutive of pinna = spiny (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 184 - 457 m (Ref. 6181), usually - m (Ref. ). Deep-water; 0°C - ; 31°N - 3°N, 94°W - 49°W (Ref. 6181)
Western Atlantic: known only from the Gulf of Mexico, Yucatán Channel, Caribbean Sea off Venezuela, off Suriname, and off southern Brazil (Ref. 47377).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 22.0 cm SL male/unsexed; (Ref. 6181)
soft rays: 17 - 20. There are two lateral lines on the sides, both originating above the upper angle of the gill opening. Sometimes the lower lateral line branches off from the second or third tubular scale of the upper lateral line. The sides are silvery, the back brown; the first dorsal fin is blackish, the second dorsal fin black anteriorly; the buccal cavity is pale, and the branchial cavity pale to dusky.

Estimates based on models
Preferred temperature (Ref. 115969
): 9.9 - 19.6, mean 16 °C (based on 46 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00438 - 0.02502), b=3.01 (2.80 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (20 of 100) .
