A small thresher with moderately large eyes, a broadly convex forehead, a very narrow caudal tip, and straight, broad-tipped pectoral fins [536].

Dark blue on back and sides, underside white; no white patch over pectoral fin bases [536].

Biology
Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed [733] (Ref. 42326). Usually with at least two young [1388]. Size at birth about 100 cm [1388]; 130-160 cm TL [2539]. Distinct pairing with embrace [17086]. A carnivore [17641]. A pelagic species occasionally advancing into coastal waters [17641].
