The fish has 13 to 21 dorsal soft rays and 12 to 23 anal soft rays. It grows up to a maximum total length of 27 cm (11 in). The distinctive feature of spotted sardinella from other two relatives is the presence of 10 to 20 golden spots along the flank. The color of spots may change into black after preservation. Belly is less rounded and scutes are not prominent.[5]
Diet
editThe fish feeds on minute organisms like copepods, larval bivalves and aquatic gastropods, and dinoflagellates like Peridinium and Ceratium.[5][3]
Human uses
editThe fish is present in fisheries throughout its range. It is often used as bait.[1] It is a widely captured commercial fish in Sri Lanka, where the fish is known as "Hurulla" in Sinhala language.[6]
