колючие лучи спинного плавника (общее число) : 5; членистые (мягкие) лучи спинного плавника (общее число) : 126 - 144; колючие лучи анального плавника: 2; членистые (мягкие) лучи анального плавника: 47 - 50. Body extremely elongate, compressed and tapering to a point. Pelvic fins reduced to scale-like processes; caudal fin absent. Lateral line running almost straight mid laterally nearer the ventral than the dorsal contour. Color is silvery white becoming silvery gray with dark cloud-like patches after death.
Body shape (shape guide): elongated; Cross section: compressed.
Benthopelagic or pelagic in coastal waters but not found where there is low salinity. Feeds mainly on small fishes, squids and crustaceans. Caught mainly with bottom trawls and sometimes with bag nets, mixed with other trichiurid fishes in southeast Asian countries. Marketed fresh and dried salted in the Philippines.
