Family:  Dorosomatidae (Gizzard shads and sardinellas)
Max. size:  12.5 cm SL (male/unsexed)
Environment:  pelagic-neritic; marine; depth range 0 - 50 m
Distribution:  Western Pacific: Taiwan and adjacent mainland China south to Hong Kong; now reported in the Philippines.
Diagnosis:  Dorsal spines (total): 0-0; Dorsal soft rays (total): 13-21; Anal spines: 0-0; Anal soft rays: 12-23. Total scutes 30 to 32. Vertical striae of scales overlapping or sometimes continuous at center of scale, numerous small perforations on hind part of scale. Tips of caudal fin lobes black, by which it differs from S. brachysoma. From other deep-bodied species in the area which have overlapping or continuous scale striae it differs in having a dark spot at dorsal fin origin.
Biology:  Forms schools in coastal waters.
IUCN Red List Status: Least Concern (LC); Date assessed: 02 March 2017 Ref. (130435)
Threat to humans:  harmless
Country info:  Specimens captured in a drift gillnet by a local fisher in the Babuyan Channel off of Santa Ana (18°30' N; 122°8' E), Cagayan Province, Philippines (Fig. 1), on 18 December 2010. Oceanographic data and life-history experiments support the working hypothesis that this species was able to cross the Luzon Strait perhaps using the Taiwanese, Batanes and Babuyan Islands as stepping stones; however, it is unclear if the species originated in the Philippines and spread to Taiwan, or originated in Taiwan and moved to the Philippines (Ref. 89007). May have split from Sardinella tawilis in the late Pleistocene based on DNA analyses (Ref. 108843).
