Maturity: Lm ?  range ? - ? cm
Max length : 61.0 cm TL maschio/sesso non determinato; (Ref. 2850)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 46 - 55; Spine anali: 0; Raggi anali molli: 40 - 43. Dorsal and anal fins very high. Dorsal fin inserted above middle of snout, the fin reaching a little behind the caudal fin base, the 4th ray much stouter than others. Dorsal and anal fins with scaly sheaths; rays of the fins not articulated. Attains 45 cm SL.
Oceanic. The species is very rare and most likely seen as stomach content of large predatory fishes, such as tunas. Young probably inhabits shallow, adult deep water.

Estimates based on models
Preferred temperature (Ref.
123201): 14.8 - 26.3, mean 23.3 °C (based on 390 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.2 ±0.6 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (tmax=9-11; very rare).
Fishing Vulnerability (Ref.
