Diagnosis: Body rather deep, its depth about 34-41% of standard length, belly with 17-20 + 9-13 scutes, total 28-32 scutes; anterior arm of pre-operculum with the third infra-orbital bone immediately above it, no fleshy gap between; mouth inferior, lower jaw strongly flared outward; last dorsal finray filamentous; pectoral axillary scale present; hind edge of scales distinctly toothed; a dark spot behind gill opening (Ref. 188). Resembles Nematalosa galatheae, which has spots along the flank and a smooth hind edge to scales; Nematalosa arabica, N. come and N. japonica all have a distinct fleshy triangular area above the anterior arm of the pre-operculum and none have toothed scale edges; no other clupeid in the distribution area of Nematalosa nasus has a filamentous dorsal finray (Ref. 188).
Known from estuaries and coastal areas, occasionally ascending into the upper reaches of the tidal zone (Ref. 12693). A filter-feeder. Marketed fresh, dried-salted or boiled. Made into fish balls. Very bony.
