Maturity: Lm 218.0  range ? - ? cm Max length : 260 cm TL 雄鱼/尚未辨别雌雄; (Ref. 1394); 最大体重: 156.0 kg (Ref. 1394)
Dorsal cape: muted blue or bluish-gray. Eye to anus flipper stripes: darker blue or bluish-black. Dark stripe subtending the eye-to-anus stripe usually present. Some individuals have distinct subtending stripe from the eye-to-anus stripe at its origin near the eye, while others the two fuse farther behind the eye only to bifurcate further posteriorly.
Inhabits warm waters (Ref. 1394). Feeds on small, mid-water squid and fish, especially lanternfish (Ref. 1394). Preyed upon by the great white shark (Ref. 36856) and blue sharks (Ref. 50255). A warm water species (Ref. 1394). Occasionally occurs in neritic habitats. Abundant in offshore and erratic over the shelf of Bay of Biscay (Ref. 81175). Feeds throughout the water column (Ref. 122680). Feeds on small, mid-water squid and fish, especially lanternfish (Ref. 1394). Although an oceanic species, they make temporary incursions over neritic and coastal habitats to feed. Oceanic prey are from mesopelagic community while neritic prey are mostly epibenthic (Ref. 81175).
