Two lateral lines, originating above the upper angle of gill opening, branching below the 4th dorsal-fin spine or slightly behind it, upper line running along the first dorsal-fin base and ending below about the end of the first dorsal fin, lower line abruptly curved backward from bifurcation, running mid laterally to the base of the middle caudal-fin ray. Body color is dark brown with slightly metallic reflections, sometimes slightly paler on belly. Dorsal fin membranes with black markings.
Morphology

Dorsal spines (total): 17 - 19; Dorsal soft rays (total): 16 - 17; Analspines: 1; Analsoft rays: 16 - 17; Vertebrae: 34
Trophic Strategy
provided by Fishbase
Mesobenthopelagic, down to depths of 400 m or more, often at the surface at night around Okinawa, Japan. The largest populations are probably on the slope of seamounts or ridges. Feeds on a variety of mesopelagic fish, squid and crustaceans.

Blacksail snake mackerel: Brief Summary
provided by wikipedia EN
The blacksail snake mackerel (Thyrsitoides marleyi), known also as the black snoek, is a species of snake mackerel found in the Indo-Pacific from shallow water to a depth of at least 400 m (1,300 ft) where they appear to prefer slopes on seamounts and ridges. They are known for making diel vertical migrations to near-surface waters at night, feeding on fish, squid and crustaceans. This species reaches a total length of 2 m (6.6 ft) though most are around 1 m (3.3 ft). This species is of minor importance to local commercial fisheries. It is at the only member of the genus Thyrsitoides, making the genus monotypic.
