Operculum absent; gill opening reduced to a vertical slit on the side of the body; gill membrane broadly united to isthmus. Dorsal and anal fins preceded by a series of 5 to 10 blade-like spines with anterior and posterior points. Pelvic fins absent. Caudal fin deeply forked, the lower lobe longer than the upper.

Inshore species, usually in schools over muddy bottoms, associated with fish species like Nemipterus and Leiognathus. Adults feed on ctenophores, salps, medusae, and other zooplankton groups. Western populations spawn from late winter through the summer with peaks from April to June. Sold fresh in local markets or shipped frozen to urban centers. Used in Chinese medicine (Ref. 12166).
