Etymology: Spratellomorpha: Old German, sprotte (1611) = a small fish, Clupea sp.+ greek,morphe = shape (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
; Água doce; estuarina pelágico(a,os,as). Tropical; 0° - 26°S, 37°E - 50°E (Ref. 188)
Africa: Madagascar (Ref. 188, 3509), probably restricted to the Majunga region (Ref. 33664). Also reported from Kenya coast at Port Tudor (Ref. 188, 117486), but whether this Mombassa material is conspecific with Spratellomorpha bianalis from Madagascar is currently unclear (Ref. 33664).

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 14 - 17; Espinhos anais: 0; Raios anais : 16 - 18; Vértebras: 45 - 46. Diagnosis: Body elongate, a little compressed; belly rounded, without pre-pelvic and post-pelvic scutes, but a pelvic scute present with slender vertical arms; gillrakers 26-31; pelvic fin with 1 unbranched and 7-8 branched finrays, well before dorsal fin origin; last two anal finrays separate, forming a distinct little finlet (Ref. 188, 117486, 121271). This species is distinguished from other clupeids by the presence of 2 anal fins, of which the second anal fin comprises 2 finrays (Ref. 188, 121271).
Presumed marine or estuarine (Ref. 188), but its reported presence in Port Tudor, an area where estuarine conditions prevail, would indicate that the species may be confined to estuaries (Ref. 117486) and it is found in fresh and brackish water in Madagascar (Ref. 13333, 117576). Maximum total length 6.0 cm (Ref. 121271).
