Etymology: Escualosa: Latin, squaleus, squalidus = with rough skin + Latin, alausa = a fish cited by Ausonius and Latin, halec = pickle, dealing with the Greek word hals = salt; it is also the old Saxon name for shad = "alli" ; 1591 (Ref. 45335).

Ecologia
marino; acqua dolce; salmastro; amfidromo (Ref. 51243); distribuzione batimetrica 0 - 50 m (Ref. 188). Tropical; 27°N - 22°S, 64°E - 151°E (Ref. 188)
Indo-West Pacific: northern Indian Ocean (Karachi eastward to Rangoon) to Thailand, Indonesia (Java Sea), the Philippines, Papua New Guinea, and Australia.
Length at first maturity / Size / Peso / Age
Maturity: Lm ?, range 7 - ? cm
Max length : 10.0 cm SL maschio/sesso non determinato; (Ref. 188); common length : 8.0 cm SL maschio/sesso non determinato; (Ref. 188); Età massima riportata: 1.00 anni (Ref. 43081)
Spine dorsali (totale): 0; Raggi dorsali molli (totale): 13-21; Spine anali 0; Raggi anali molli: 14 - 19. Belly strongly keeled. The almost rectangular second supra-maxilla and the bright silver stripe along the flank distinguish it from juveniles of Sardinella, Amblygaster and Herklotsichthys. Resembles some pellonulines with a silver stripe, but they lack a first supra-maxilla. Distinguished from E. elongata of the Gulf of Thailand but its deeper body and broader silver stripe.
Forms schools in shallow waters, the juveniles apparently entering the lower parts of rivers, but returning later to the sea. Feeds on both zooplankton (copepods, crab zoea, larvae of bivalves and fish eggs) and phytoplankton. Breeds from October to February (mainly November to January) off western coast of India, usually in relatively shallow inshore waters. Marketed fresh and dried-salted.
