Etymology: Pteraclis: Greek, pteron = wing, fin + Greek, aklisia, -as = invariable (Ref. 45335).
More on authors: Jordan & Snyder.
Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; oceanodromous (Ref. 51243); depth range 0 - 100 m (Ref. 58302). Temperate

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 61.0 cm TL male/unsexed; (Ref. 2850)
soft rays: 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.
