Info
The black snoek belongs to the family of fishes that also includes escolar, gemfish and snake mackerel.
Thyrsitoides marleyi is a dark, metallic brown snook that becomes paler on the ventral side, with a black pattern on the first dorsal fin membrane.
Two lateral lines beginning above the upper angle of the gill opening and branching below or slightly behind the 4th dorsal fin spine, the upper line running along the first dorsal fin attachment and ending approximately below the end of the first dorsal fin, the lower line abruptly curving backward from the branching point and running centrally laterally to the attachment of the middle caudal fin ray. Body color is dark brown with light metallic reflections, sometimes slightly paler on the belly. Dorsal fin membranes with black markings.
The animal lives mesopelagic to benthopelagic to depths of 400 m or more, the fish often comes to the surface at night, for example around Okinawa, Japan.
The largest populations of the species are probably on the slopes of seamounts or ridges.
This large predator feeds on a variety of mesopelagic fish (largely from the Myctophidae family), squid, and crustaceans
The Black Snoek has a very elongated, compressed body, a large mouth with huge, tooth-like teeth on the front of the upper jaw.
There are cartilaginous appendages on the front of both jaws.
This species has well-developed pelvic fins and a caudal peduncle without keels.
There are two lateral lines - one high on the back and the other on the middle of the body.
Habitat: Tropical and temperate waters of the Indo-West Pacific.
Synonyms:
Mimasea taeniosoma Kamohara, 1936
Thrysitoides marleyi Fowler, 1929
Thyrisitoides marleyi Fowler, 1929
Thyrsitoides jordanus Ajiad, Jafari & Mahasneh, 1987
